Beschreibung: Ocean warming is causing declines of coral reefs globally, raising critical questions about the potential for corals to adapt. In the central equatorial Pacific, reefs persisting through recurrent El Niño heatwaves hold important clues. Using an 18-year record of coral cover spanning three major bleaching events, we show that the impact of thermal stress on coral mortality within the Phoenix Islands Protected Area (PIPA) has lessened over time. Disproportionate survival of extreme thermal stress during the 2009–2010 and 2015–2016 heatwaves, relative to that in 2002–2003, suggests that selective mortality through successive heatwaves may help shape coral community responses to future warming. Identifying and facilitating the conditions under which coral survival and recovery can keep pace with rates of warming are essential first steps toward successful stewardship of coral reefs under 21st century climate change.

Beschreibung: The Intergovernmental Oceanographic Commission (IOC-UNESCO) has functional autonomy within UNESCO. It is the only UN body specializing exclusively in ocean science, ocean observation, ocean data and information exchange and dedicated ocean services such as Tsunami Early Warning Systems. In 2019, UNESCO’s Intergovernmental Oceanographic Commission was tasked to lead the UN Decade of the Ocean. This opportunity, combined with a fast-evolving ecosystem of international actors in an expanding and increasingly crowded ocean policy and marine science space, prompted IOC-UNESCO to request an evaluation of IOC-UNESCO with a focus on its strategic positioning within the UN system and the broader landscape of ocean-related actors and programmes to meet the high demand for sound ocean science in an oceanographic space. The evaluation found that IOC-UNESCO is a valued partner for Member States as well as other international and national actors, and indispensable for strengthening capacities and providing the data and technical information on ocean science policy that serves as a basis for national level data. IOC-UNESCO has been most successful in providing contributions to UN Frameworks and Conventions (e.g. UNFCCC, Sendai and CBD), in acting as a neutral platform to discuss the increasingly relevant issue of ocean health and climate change, in bringing Member States together and fostering exchanges between governments and scientists, as well as in providing to the extended oceanographic community access to data, information and science. However, strategic advocacy at the national level, engagement at the regional level, and resourcing and visibility of gender equality and women’s empowerment in the ocean space within and outside IOC-UNESCO are among the areas where further improvements are required. The establishment of the Decade of Ocean Science for Sustainable Development is the most important strategic institutional achievement of IOC-UNESCO in recent years. It is an important opportunity, but the absence of a clearly defined results framework and inadequate resources could jeopardize its success. Furthermore, it still needs to be determined how to best exploit IOC-UNESCO’s data and knowledge base and how UNESCO can best support the Decade, among other through intersectoral work.

Beschreibung: Oceanographic data, when well-documented and stewarded toward preservation, have the potential to accelerate new science and facilitate our understanding of complex natural systems. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) is funded by the NSF to document and manage marine biological, chemical, physical, and biogeochemical data, ensuring their discovery and access, and facilitating their reuse. The task of curating and providing access to research data is a collaborative process, with associated actors and critical activities occurring throughout the data’s life cycle. BCO-DMO supports all phases of the data life cycle and works closely with investigators to ensure open access of well-documented project data and information. Supporting this curation process is a flexible cyberinfrastructure that provides the means for data submission, discovery, and access; ultimately enabling reuse. Based upon community feedback, this infrastructure is undergoing evaluation and improvement to better meet oceanographic research needs. This poster will introduce the repository and describe some of the strategic enhancements coming to BCO-DMO, and presents an opportunity for you to provide feedback on enhancements yet to come. We invite you to think about your own research workflow of searching and accessing new data for research, and to provide your feedback through the poster’s interactive sections. Your input can help BCO-DMO improve its service to the research community. For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'.

Beschreibung: The importance of studying the radiocarbon content of dissolved inorganic carbon (DI14C) in the oceans has been recognized for decades. Starting with the GEOSECS program in the 1970s, 14C sampling has been a part of most global survey programs. Early results were used to study air-sea gas exchange while the more recent results are critical for helping calibrate ocean general circulation models used to study the effects of climate change. Here we summarize the major programs and discuss some of the important insights the results are starting to provide.

Ecology Letters, 25(8), (2022): 1854-1868, https://doi.org/10.1111/ele.14066.

Beschreibung: Spatial synchrony is a ubiquitous and important feature of population dynamics, but many aspects of this phenomenon are not well understood. In particular, it is largely unknown how multiple environmental drivers interact to determine synchrony via Moran effects, and how these impacts vary across spatial and temporal scales. Using new wavelet statistical techniques, we characterised synchrony in populations of giant kelp Macrocystis pyrifera, a widely distributed marine foundation species, and related synchrony to variation in oceanographic conditions across 33 years (1987–2019) and 〉900 km of coastline in California, USA. We discovered that disturbance (storm-driven waves) and resources (seawater nutrients)—underpinned by climatic variability—act individually and interactively to produce synchrony in giant kelp across geography and timescales. Our findings demonstrate that understanding and predicting synchrony, and thus the regional stability of populations, relies on resolving the synergistic and antagonistic Moran effects of multiple environmental drivers acting on different timescales.

D.C.R. and L.W.S. were also partly supported by NSF award 1714195, the McDonnell Foundation, and the California Department of Fish and Wildlife Delta Science Program. This project used data developed through the Santa Barbara Coastal Long Term Ecological Research project, funded through NSF-OCE award 1831937.

Beschreibung: The gap in our understanding of Earth is largely because resources have been more readily allocated to exploring the surface of other planets, as well as the fact that mapping beneath water is a complex business, especially at great depths. Water absorbs, reflects and refracts light to such an extent that it is difficult to “see” through it with visual media for more than a few dozen metres. Huge swathes of the oceans, especially those far removed from coastal and national areas, are still inadequately mapped. Environments such as those beneath the polar ice shelves and pack ice-covered oceans are as unfamiliar to us today as the deep ocean was for pioneering ocean-floor mappers over a hundred years ago. But today, with the advent of satellite mapping, multibeam sonar and other advances in remote sensing, we have access to an increasingly broad suite of technologies which make it possible to map the world’s seafloor in more detail than ever.

Coral Reefs, 41, (2022.): 1031–1043, https://doi.org/10.1007/s00338-022-02272-5.

Beschreibung: Decades of research have revealed relationships between the abundance of coral reef taxa and local conditions, especially at small scales. However, a rigorous test of covariation requires a robust dataset collected across wide environmental or experimental gradients. Here, we surveyed spatial variability in the densities of major coral reef functional groups at 122 sites along a 70 km expanse of the leeward, forereef habitat of Curaçao in the southern Caribbean. These data were used to test the degree to which spatial variability in community composition could be predicted based on assumed functional relationships and site-specific anthropogenic, physical, and ecological conditions. In general, models revealed less power to describe the spatial variability of fish biomass than cover of reef builders (R2 of best-fit models: 0.25 [fish] and 0.64 [reef builders]). The variability in total benthic cover of reef builders was best described by physical (wave exposure and reef relief) and ecological (turf algal height and coral recruit density) predictors. No metric of anthropogenic pressure was related to spatial variation in reef builder cover. In contrast, total fish biomass showed a consistent (albeit weak) association with anthropogenic predictors (fishing and diving pressure). As is typical of most environmental gradients, the spatial patterns of both fish biomass density and reef builder cover were spatially autocorrelated. Residuals from the best-fit model for fish biomass retained a signature of spatial autocorrelation while the best-fit model for reef builder cover removed spatial autocorrelation, thus reinforcing our finding that environmental predictors were better able to describe the spatial variability of reef builders than that of fish biomass. As we seek to understand spatial variability of coral reef communities at the scale of most management units (i.e., at kilometer- to island-scales), distinct and scale-dependent perspectives will be needed when considering different functional groups.

Beschreibung: In 2017, the UN General Assembly declared the UN Decade of Ocean Science for Sustainable Development (2021-2030). It has entrusted IOC-UNESCO with the design and delivery of the Decade to ensure that ocean science is indeed underpinning sustainable ocean management and the 2030 Sustainable Development Agenda more broadly. Fulfilling its mandate as trustee of the Ocean Decade, as well as delivering on a growing list of additional roles, in an oceanographic space that is both expanding and increasingly crowded, establishes an important opportunity but also an overarching challenge for IOC-UNESCO. In the context of the upcoming UN Decade of the Ocean, the IOC-UNESCO agreed with the Internal Oversight Service (IOS) on the merit of conducting an evaluation of its strategic positioning within the UN system and the broader landscape of ocean-related actors and programmes, taking into account relevant enabling policy frameworks to which the work of the Commission responds.

Beschreibung: This event entitled “Verso la Generazione Oceano” (Towards the Generation Ocean) was the first initiative organized in Italy to present the United Nations Decade of Ocean Science for Sustainable Development (hereinafter the “Decade”). It was held on 22 October 2020 in Milan, Italy. Its goal was to illustrate to the Italian stakeholders the objectives and the plans of the Decade in order to pave the way for the creation of the Generation Ocean campaign (#versolagenerazioneoceano) that will be developed in Italy in 2021. Moreover, this event was organized with the aim to work with different stakeholders and sectors of the society in start developing ideas to be implemented during the UN Decade of Ocean Science for Sustainable Development (2021–2031). This event was planned to take place in May 2020 and the preparatory work started in January 2020. However, due to the Covid-19 outbreak, it was postponed and rescheduled as a digital event to 22 October 2020. Nutrition, oxygen, energy, work, health: everything that allows us to live is linked to the ocean. To promote greater knowledge, conservation and sustainable use of the ocean and its resources, the United Nations declared 2021-2030 "Decade of Ocean Science for Sustainable Development". The Decade aims to mobilise the scientific community, policymakers, business and civil society around a collaborative research and technological innovation programme. It will enable the coordination of research programmes, observation systems, capacity building, maritime spatial planning, and marine risk reduction, to improve the management of ocean and coastal zone resources. The Decade of Ocean Sciences should accelerate the implementation of Sustainable Development Goal 14 for the conservation and sustainable use of the ocean, seas and marine resources. The goal is also to create together “the ocean we need, for the future we want”. With this in mind, the UNESCO Regional Bureau for Science and Culture in Europe and the Intergovernmental Oceanographic Commission of UNESCO (IOC-UNESCO) represented by its Executive Secretary, Dr Vladimir Ryabinin, organised a popular event "Towards the Generation Ocean" to present in Italy the Decade of Ocean Science. In collaboration with various partners, the event aims to initiate a movement that gives voice to the importance of having a resilient ocean, a productive ocean and a healthy ocean. The event focussed on three great challenges: "climate change, food safety and human health". From the No’hma theatre in Milan, “Towards the Generation Ocean” gathered virtually from 9 a.m. to 1 p.m., researchers, professionals, sustainable entrepreneurs, and also chefs, musicians, journalists and experts from various sectors of society. The time to act is now and we must act together! was the message. The event was an initiative dedicated to the role of marine scientific research as an essential tool to ensure the health of the planet and the announcement of a new era represented by the "Generation Ocean". It strived to spread greater awareness of the importance of the ocean and to promote innovative solutions to the challenges we will face in the coming years. At the end of the morning, the event hosted the award ceremony of Oceanthon, the digital hackathon aimed at students, researchers, developers, experts in communication, economics, marketing and design, participating in the design of innovative ideas for the conservation of the ocean. The highlight of the mobilisation event was the presentation of the Oceanthon Prize by Davide Villa, CMO and Board Member of E.ON Italia to the winning “River Cleaner” project by Blue Eco Line startup. The initiative mobilized institutions, companies, non-profit organizations, media and popular people with great interest in the objectives of the Decade. All of them are called to become the promoters of specific initiatives and helper of the IOC as coordinator of the Decade in raising awareness, and facilitating stakeholders’ commitments for the Decade.
