Description: Dissociation of methane hydrates due to ocean warming releases methane, a powerful greenhouse gas, to the atmosphere. Dissociation of gas hydrates may have led to rapid and dramatic environmental changes in the past. Thus, understanding the impact of those events requires information about their timing and magnitudes. While the foraminiferal fossil record provides a powerful tool to understand past environmental conditions, seep-endemic foraminifera are unknown, which limits evaluation of seep-specific information. However, geographically widespread benthic foraminifera do inhabit seep sites, as documented widely in the literature, and may provide information useful to the understanding of past methane releases. In an effort to better understand how benthic foraminifera inhabit this chemosynthesis-based ecosystem, and if they faithfully record the methane emissions, we conducted a multipronged analysis of foraminifera associated with a gas hydrate emission site in the Arctic. Our goal was to simultaneously assess, in single representative calcareous benthic foraminiferal individuals, the cell biology, test stable carbon isotope ratio, and carbonate microstructure (e.g., wall thickness, survey for authigenic overgrowths), from samples collected south of Svalbard, or on Vestnesa Ridge, west of Svalbard). Serially, each specimen was scanned with microCT (computerized tomography) to assess test characteristics, then the test dissolved by acidification while capturing gas to measure stable carbon isotope ratio via continuous-flow mass spectrometry, and finally the remaining soft parts embedded and examined for cell ultrastructure with a Transmission Electron Microscope (TEM). TEM). Data from isotopic analyses, microCT scans and TEM imaging are presented here.

Description: High-frequency radar-based observations of surface currents along the east coast of Taiwan, obtained over a 50-day period in early 2017, are used to examine the occurrence, generation, and downstream advection of submesoscale eddies in the Kuroshio. Measured at an effective depth of 2 m and radial resolution of 3 km from four land-based HF radar systems spanning an 250-km along-stream distance, the surface current observations reveal the instantaneous position of the Kuroshio on hourly time scales as well as the occurrence of numerous high relative vorticity features. Vortex features with spatial scales of 5-20 km were concentrated in the first 30 km offshore, with many created at the southern tip of Taiwan on tidal timescales. Most features, with relative vorticities approaching zeta/f=1, translated northward along the coast at the speed of the Kuroshio itself and were coherent over the 250-km length of the Taiwanese coastline. Both tides and regional winds appear to influence when long-lived features form, and the offshore advection of surface waters by the vortices are observable in intermittent Satellite images of surface chlorophyll. While most features are advected northward with the current, a submarine ridge acts to impede the flow, scattering northward moving features and causing occasional southward-migrating vortices. Data Description: DESCRIPTION; The surface current observations used here were obtained from four long-range (4 MHz transmit frequency) land-based coastal radar systems, operated by the Taiwan Ocean Research Institute (TORI) and the National Taiwan University (NTU). All systems were Codar Ocean Sensors SeaSondes, with the three southern stations operated by TORI, and the northern-most station by NTU. Collected over the time period spanning February 1st to March 26th, 2017, the hourly observations of Doppler cross-spectra had a radial resolution of 3 km. Horizontal resolution was dependent on both the resolution of the measured antenna patterns (1 degree in azimuth) as well as the inherent azimuthal resolution of the radar returns themselves. DATA_PREPARATION_DESCRIPTION; Observed Doppler cross-spectra were reprocessed following Kirincich et al. (2012) using adjusted measured antenna patterns and advanced quality control metrics to estimate the radial surface currents observed at each site. Measured antenna response patterns were adjusted iteratively to reduce radar-to-radar inconsistencies defined using synthetic radials estimated from adjacent radars as well as systematic biases in mean vorticity and divergence patterns. Vector combinations of the radial surface currents, representative of the average currents over the top 2 m of the water column (StewartJoy, 1974) were estimated using power-weighed least-squares methods (Kirincich et al. 2012, Kaplan et al 2005) with a fixed horizontal averaging length-scale of 3 km, and masked for errors due to the geometric dilution of precision (GDOP) greater than 2 (Barrack, 2002). Acquisition Description: SENSOR_INFORMATION; Radio frequency interference from the ionosphere is a particular problem for the TORI and NTU radars, due to a combination of latitude and transmit frequency, causing elevated background noise during local nighttime. Returns at ranges of 90 km, the distance to the primary scattering layer within the ionosphere, are especially affected. SNR was used as an effective screening tool to isolate and eliminate data contaminated by ionospheric radio noise common in the region, adding further improvements to the radial velocity results. However, data from a 50x50 km region directly offshore of the radar site near 23deg 30' N 121deg 30' E was excised during the hours of 11 to 17 UTC each day during the observational period due to poor data returns during times of high ionospheric reflections and radio noise that resulted in poorly resolved and inaccurate vector current estimates. Using synthetic radials from adjacent HFR sites (Emery et al 2019), surface current uncertainties are estimated to be 5-10 cm/s. the west of the 2018-2019 mooring locations. The surface mooring was located at 41.0706degN 70.8177degW in 40 m of water and sampled surface vector winds, air temperature, air pressure, and relative humidity using a Vaisala WXT520 located at 2 m above mean sea level at 10 min ensemble averages, of 1 Hz data. The 2020 surface mooring also had 5 temperature-conductivity sensors (SBE37s) that sampled the oceanic water column at fixed depths below the surface of 0.6,4,6.5,10, and 20-m at 2 min increments. Finally the 2020 subsurface mooring was deployed at 41.0706degN 70.8177degW and contained a sub-surface float at 8-m below sea level in 40 m of water. The float held an upward looking Nortek Signature 1000 AD2CP that collected 2048 pings @4Hz every 20 min at 0.25 m bin depths.

Description: The Northwest Tropical Atlantic Station (NTAS) was established to address the need for accurate air-sea flux estimates and upper ocean measurements in a region with strong sea surface temperature anomalies and the likelihood of significant local air–sea interaction on interannual to decadal timescales. The approach is to maintain a surface mooring outfitted for meteorological and oceanographic measurements at a site near 15°N, 51°W by successive mooring turnarounds. These observations are used to investigate air–sea interaction processes related to climate variability. The NTAS Ocean Reference Station (ORS NTAS) is supported by the National Oceanic and Atmospheric Administration’s (NOAA) Global Ocean Monitoring and Observing (GOMO) Program (formerly Ocean Observing and Monitoring Division). This report documents recovery of the NTAS-17 mooring and deployment of the NTAS-18 mooring at the same site. Both moorings used Surlyn foam buoys as the surface element. These buoys were outfitted with two Air–Sea Interaction Meteorology (ASIMET) systems. Each system measures, records, and transmits via satellite the surface meteorological variables necessary to compute air–sea fluxes of heat, moisture and momentum. The upper 160 m of the mooring line were outfitted with oceanographic sensors for the measurement of temperature, salinity and velocity. The mooring turnaround was done by the Upper Ocean Processes Group of the Woods Hole Oceanographic Institution (WHOI), onboard R/V Ron Brown, Cruise RB-20-01. The cruise took place between January 6 and 26 2020. The NTAS-18 mooring was deployed on January 10, and the NTAS-17 mooring was recovered on January 15. Inter-comparison between ship and buoys were performed on this cruise. This report describes these operations, as well as other work done on the cruise and some of the pre-cruise buoy preparations. Other operations during RB-20-01 consisted in the acoustic communications with the Meridional Overturning Variability Experiment (MOVE) subsurface mooring array MOVE 1-13 and acoustic downloads of data from Pressure Inverted Echo Sounders (PIES) was also conducted at MOVE 1. MOVE is designed to monitor the integrated deep meridional flow in the tropical North Atlantic. Two ARGO floats were also deployed on behalf of the WHOI ARGO group. During the cruise, atmospheric measurements of aerosols, as well as radar, Lidar, radiosondes were made as part of the ATOMIC campaign. 3

Description: The following lists actual and relative positions for 2 critical pieces in the AMPHORA Site - the WRECK and the BROKEN AMPHORA. First some comments. All LAT/LON positional data are referenced to GPS. The actual positions froM the STARELLA 88 data are reliable. The actual position (only located the broken AMPHORA on that trip) from the KNORR 88 data is not reliable for reasons which are detailed in a separate note to Tom Crook. In which case, the relative positions are important. From the relative positions of the 2 wreck locations, one can safely say that there is only one wreck in that area. The broken AMPHORA is the only tie between the two coordinate systems. This is assuming that there is only one, unique broken amphora. Uchupi believes this is the case. However, the possibility that there is more than one has not been completely ruled out. Considering the proximity of the wreck to the broken amphora based on the STARELLA 88 data, it seems implausible that you would have Missed the wreck completely once you found the broken amphora. This is what preserves the possibility of more than one, at least for the Moment. More careful and detailed examination of the KNORR 88 data tracks should indicate if you indeed went through an area located relative to the broken amphora where the wreck should have been. I haven't had time to examine the data myself yet.

Description: Information is presented on the structural and functional properties of phosphates in "biochemical systems. Phosphates follow four structural formation principles: (1) linkage of phosphate units via oxygen co-ordinated metal ion polyhedra, (2) establishment of chains, (3) cross linkages of chains resulting in corrugated layers, and (4) cross linkages of layers resulting in distinct three-dimensional molecular networks. One Iinkage type does not require nor exclude another Iinkage type. On the basis of this concept on the associations of phosphate tetrahedra and metal ion oxygen polyhedra, a revised molecular model for DNA is proposed. Metal ion oxygen polyhedra excercise control on the shape of the DNA, and thus may introduce the stretching of the polymer chains This can be considered the ultimate reason why a single stranded DNA will associate itself readily with another single stranded DNA resulting in a double helix. In contrast, the coupling of a single stranded DNA by itself in making a sharp bend (loop) will not take place due to the stabilization of the structure by means of the metal ion oxygen polyhedra backbone. This model also explains thefunctional properties of the nucleic acids, for instance, the oxide chains and layers will favor proton jumps, and in the presence of a differential potential, they will form proton conduction bands. The molecular organization, as introduced by the association of metal ion coordination polyhedra with the PO4 groups, plays also a significant role in membrane dynamics. Analogous to the ion co-ordination interactions of polyphosphoric acids, the fixation of metal ions at the P-O surface and of membranes will result in a distinct molecular geometry as a whole. In this way, the membranes will act as dynamic molecular sieves, whereby the mesh size and the functional characteristics of these molecular sieves is determined by the flexible interplay of metals and the individual phospholipid compounds contained in the membranes. TP (111-P) is characterized for its ability to form a co-ordination polyhedron with polyvalent cations. In this way it resembles polyphosphates and differs from 1-P and 11-P. Triphosphate exhibits two significant properties: (1) terminal chain degradation, i.e. the release of terminal PO4 groups and formation of PO3 radicals which is controlled by external electrical forces,and (2) affinity to all cations by means of metal ion oxygen polyhedra and the establishment of an exchange affinity series for all metal ions. Concerning the biosynthesis of polysaccharides, proteins, and the nucleic acids, three conditions have to be fulfilled;. (1) acitvation of the react ion partner, (2) maximum efficiency and minimum error, and (3) well-defined control of the reactions in terms of kinetics and transportation mechanism. All three requirements are most effectively executed by triphosphates. The controlled formation of the reactive P03 radicaI not only activates the reaction partner, but also eliminates by means of the phosphate formation, the OH and O groups from the reaction system and this with extraordinary efficiency and elegance. In biochemical reactions, this role is commonly exercised by ATP.

Description: The objectives of R/V Neil Armstrong cruise AR35-04 (Fig. 1) were to survey the flanks of the Reykjanes Ridge and determine the timing, geometry and associated geophysical characteristics of the large-scale tectonic reorganizations that occurred there in the Paleogene and continue to the present (Fig. 2). The North Atlantic plate boundary between what is today the Bight Fracture Zone and Iceland, a distance of nearly 1000 km, was originally a linear orthogonally-spreading ridge that became abruptly fragmented in a stair-step fashion following a change in plate motion [Smallwood and White, 2002]. Its subsequent evolution involved the systematic and progressive removal of offsets from north to south to re-establish its original linear configuration [Hey et al., 2016; Martinez and Hey, 2017], even though this required the ridge to then spread obliquely, since the new spreading direction remained stable. These tectonic reorganizations took place within the region of influence of the Iceland “hotspot” which creates a strong gradient in mantle melting along the ridge, increasing crustal thicknesses by ~3-4 km and decreasing ridge axis depths by ~ 3000 m between the Bight Fracture Zone and Iceland [Louden et al., 2004]. A mantle gradient in melting properties (compositional and/or thermal) is presumably what results in the regional residual basement depth anomaly that extends throughout this region of the North Atlantic from the Greenland-Iceland-Faroe Ridge to south of the Bight Fracture Zone. This gradient in mantle properties with distance from the Iceland hotspot apparently had strong modulating effects on the tectonic reorganizations: the initial segment lengths and offsets appear in regional magnetic anomaly and satellite-derived gravity maps to be smaller toward Iceland and the segments evolved to re-establish the linear ridge configuration more quickly to the north [Hey et al., 2016]. As both kinematic and “hotspot” effects influence their development, the Reykjanes ridge flanks are key areas for investigating lithospheric and mantle controls on ridge segmentation, formation and elimination of transform faults and the mechanisms controlling their evolution.

Description: Following an order of Massachusetts Clean Energy Center a calibration of a LiDAR of the type WindCube V2 by Leosphere (WLS7-436) against a met mast has been performed at a test site in the US. In this report the measurement results of the LiDAR device are compared to those from calibrated cup anemometers mounted on a met mast. The aim of this comparative assessment is to convey traceability to international standards of this particular LiDAR unit. The evaluation process is based on the IEC 61400-12-1 Ed. 2 Annex L [2]. This standard describes the calibration procedure of remote sensing devices in the frame of power curve measurements on wind turbines. However, this approach generally also applies in the field of wind resource assessment, under the recommendations of MEASNET [4]. The data of the LiDAR measurement (130 m, 125 m, 95 m and 60 m) have been compared with the measured met mast data at 4 different heights (130 m, 125 m, 94 m and 58 m) during a period of 36 days (2019.08.20 – 2019.09.25) for wind speed bins between 4 – 16 m/s and for the wind direction sector 67 – 354°. In addition, measurement results of the met mast and LiDAR unit have been compared in terms of turbulence intensity, wind direction and wind shear. UL was not involved in the installation of the instruments on the mast but has gathered all relevant information. However, UL was responsible for the installation of the LiDAR unit close to the mast. It is ensured that the results presented in this report have been measured in an unbiased manner, following the best practices and to the best knowledge of the participating persons.

Description: The MBLWHOI Library’s Institutional Repository (IR) is a CoreTrustSeal certified repository. We chose to go through this process to demonstrate our commitment to quality stewardship and to be a trusted option for our researchers facing funder and publisher requirements that data be accessible, and more recently, also citable with a DOI. The Library always recommends that researchers deposit data in an appropriate subject or community repository, but there are many cases where the dataset needing a DOI does not fit that scenario. The ability to quickly and easily deposit data in a certified repository is a value added service for our users. Some funders now mandate the data must be deposited in a FAIR repository. Being a CoreTrustSeal certified repository ensures that the MBLWHOI Library’s Institutional Repository practices FAIR principles. This lighting talk will show the steps we went through to become certified, some of the hurdles and benefits, as well our current status as an application reviewer. This process enabled us to review our internal process and procedures and re-examine any outdated practices. It shined a light on places we could improve our documentation and more clearly state our policies. The importance of demonstrating our commitment to quality and the Library’s continued efforts with the repository to remain on the forefront of technology with linked open data, schema.org, etc.

Description: The Surface Ocean – Lower Atmosphere Study (SOLAS) (http://www.solas-int.org/) is an international research initiative focused on understanding the key biogeochemical-physical interactions and feedbacks between the ocean and atmosphere that are critical elements of climate and global biogeochemical cycles. Following the release of the SOLAS Decadal Science Plan (2015-2025) (Brévière et al., 2016), the Ocean-Atmosphere Interaction Committee (OAIC) was formed as a subcommittee of the Ocean Carbon and Biogeochemistry (OCB) Scientific Steering Committee to coordinate US SOLAS efforts and activities, facilitate interactions among atmospheric and ocean scientists, and strengthen US contributions to international SOLAS. In October 2019, with support from OCB, the OAIC convened an open community workshop, Ocean-Atmosphere Interactions: Scoping directions for new research with the goal of fostering new collaborations and identifying knowledge gaps and high-priority science questions to formulate a US SOLAS Science Plan. Based on presentations and discussions at the workshop, the OAIC and workshop participants have developed this US SOLAS Science Plan. The first part of the workshop and this Science Plan were purposefully designed around the five themes of the SOLAS Decadal Science Plan (2015-2025) (Brévière et al., 2016) to provide a common set of research priorities and ensure a more cohesive US contribution to international SOLAS.

Description: This data was collected by a team led by Kirincich as part of a Metocean monitoring campaign sponsored by the Massachusetts Clean Energy Center (MassCEC). The campaign was designed to observe key atmospheric and ocean parameters at an existing offshore platform in the proximity of the Massachusetts and Rhode Island Wind Energy Areas. The campaign supported the purchase and installation of a LIDAR wind profiler, two cup anemometers and a wind direction vane at the MVCO Air-Sea Interaction Tower (ASIT). These instruments were installed and operated by WHOI and validated by UL-AWS Truepower following a MetOcean Measurement Plan created by UL-AWST, WHOI, and the MassCEC. All instruments were installed on WHOI's offshore tower in the fall of 2016 and operated continuously, as possible, through the end of 2020. After this time the project transitioned to become the MetOcean Reference Site (MORS-1), supported by the National Offshore Wind Research and Development Consortium (NOWRDC).

Description: The Northwest Tropical Atlantic Station (NTAS) was established to address the need for accurate air-sea flux estimates and upper ocean measurements in a region with strong sea surface temperature anomalies and the likelihood of significant local air–sea interaction on interannual to decadal timescales. The approach is to maintain a surface mooring outfitted for meteorological and oceanographic measurements at a site near 15°N, 51°W by successive mooring turnarounds. These observations will be used to investigate air–sea interaction processes related to climate variability. This report documents recovery of the NTAS-18 mooring and deployment of the NTAS-19 mooring at the same site. Both moorings used Surlyn foam buoys as the surface element. These buoys were outfitted with two Air–Sea Interaction Meteorology (ASIMET) systems. Each system measures, records, and transmits via Argos satellite the surface meteorological variables necessary to compute air–sea fluxes of heat, moisture and momentum. The upper 160 m of the mooring line were outfitted with oceanographic sensors for the measurement of temperature, salinity and velocity. Deep ocean temperature and salinity are measured at approximately 38 m above the bottom. The mooring turnaround was done on the National Oceanic and Atmospheric Administration (NOAA) Ship Ronald H. Brown, Cruise RB-20-06, by the Upper Ocean Processes Group of the Woods Hole Oceanographic Institution. The cruise took place between 14 October and 1 November 2020. The NTAS-19 mooring was deployed on 22 October, with an anchor position of about 14° 49.48° N, 51° 00.96° W in 4985 m of water. A 31-hour intercomparison period followed, during which satellite telemetry data from the NTAS-19 buoy and the ship’s meteorological sensors were monitored. The NTAS-18 buoy, which had gone adrift on 28 April 2020, was recovered on 20 October near 13° 41.96° N, 58° 38.67° W. This report describes these operations, as well as other work done on the cruise and some of the pre-cruise buoy preparations.

Description: The purpose of the Brazil Basin Tracer Release Experiment is to measure diapycnal (across isopycnal) mixing and epipycnal (along-isopycnal) mixing and stirring in the deep ocean. This cruise is the fourth in the overall experiment. In the first cruise in early 1996, 110 kg of sulfur hexafluoride (SF6) were released on an isopycnal surface near 4000 meters depth in the eastern part of the basin on the flanks of the Mid-Atlantic Ridge (MAR). The location of the release was near 21.7 S, 18.4 W. The release site was over a zonal valley that leads to the MAR and is about 5000 m deep. The isopycnal surface of the release was defined as the surface on which the potential density anomaly, referenced to 4000 dbar pressure, was 45.9408 kg/m3. The release streaks and results of initial sampling in 1996 are described in Polzin et al. [1997].

Description: The Ocean Reference Station at 20°S, 85°W under the stratus clouds west of northern Chile is being maintained to provide ongoing climate-quality records of surface meteorology, air-sea fluxes of heat, freshwater, and momentum, and of upper ocean temperature, salinity, and velocity variability. The Stratus Ocean Reference Station (ORS Stratus) is supported by the National Oceanic and Atmospheric Administration’s (NOAA) Climate Observation Program. It is recovered and redeployed annually, with past cruises that have come between October and May. This cruise was conducted on the Chilean research vessel Cabo de Hornos. During the 2018 cruise on the Cabo de Hornos to the ORS Stratus site, the primary activities were the recovery of the previous (Stratus 16) WHOI surface mooring, deployment of the new Stratus 17 WHOI surface mooring, in-situ calibration of the buoy meteorological sensors by comparison with instrumentation installed on the ship, CTD casts near the moorings. The Stratus 17 had parted from its anchor site on January 4 2018, so its recovery was done in two separate operations: first the drifting buoy with mooring line under it, then the bottom part still attached to the anchor. Surface drifters and ARGO floats were also launched along the track.

Description: This collection of brief "summaries of investigations" has been prepared by the members of the research staff of the Woods Hole Oceanographic Institution and this volume is a continuation of our early traditions. For the first decade or so reports of progress by individual investigators were included as an appendix to each annual report. There were only fourteen such summaries occupying less than seven pages in the 1931 Annual Report; there were but thirteen persons on the research staff at that time. With the expansion of the Institution during the World War II years it became impractical to include a comprehensive report of progress for each investigator, but the Annual Reports did continue to describe very briefly the work being done by each. With the continued expansion of the Institution the printed annual report has become more and more impersonal and the lack of a comprehensive summary of current investigations has been apparent to all. The Collected Reprints of the Institution have continued to provide a record of the scientific results obtained by our staff members, but publication delays make these at least a year out-of-date before they appear. This report is the sixth in the series of Summaries of Investigations. They are similar in style to the reports of progress included as appendices to earlier Annual Reports and a limited number of copies is available. This collection of summaries is intended not only to supplement the limited information about the scientific investigations included in the Annual Report for 1967, but also to let our friends and associates know what each individual staff member is currently studying. These summaries have been reviewed by the department chairmen but typed, insofar as possible, without editorial change, adhering strictly to the original manuscript in most cases.
