    Production, oxygen uptake, and sinking velocity of copepod fecal pellets originated from the central North Sea (2010)
    PANGAEA
    In:  Supplement to: Ploug, Helle; Iversen, Morten Hvitfeldt; Koski, Marja Kaarina; Buitenhuis, Erik Theodoor (2008): Production, oxygen respiration rates, and sinking velocity of copepod fecal pellets: direct measurements of ballasting by opal and calcite. Limnology and Oceanography, 53(2), 469-476, https://doi.org/10.4319/lo.2008.53.2.0469

    Description: Production, oxygen uptake, and sinking velocity of copepod fecal pellets egested by Temora longicornis were measured using a nanoflagellate (Rhodomonas sp.), a diatom (Thalassiosira weissflogii), or a coccolithophorid (Emiliania huxleyi) as food sources. Fecal pellet production varied between 0.8 pellets ind**-1 h**-1 and 3.8 pellets ind**-1 h**-1 and was significantly higher with T. weissflogii than with the other food sources. Average pellet size varied between 2.2 x 10**5 µm**3 and 10.0 x 10**5 µm**3. Using an oxygen microsensor, small-scale oxygen fluxes and microbial respiration rates were measured directly with a spatial resolution of 2 µm at the interface of copepod fecal pellets and the surrounding water. Averaged volume-specific respiration rates were 4.12 fmol O2 µm**-3 d**-1, 2.86 fmol O2 µm**-3 d**-1, and 0.73 fmol O2 µm**-3 d**-1 in pellets produced on Rhodomonas sp., T. weissflogii, and E. huxleyi, respectively. The average carbon-specific respiration rate was 0.15 d**-1 independent on diet (range: 0.08-0.21 d**-1). Because of ballasting of opal and calcite, sinking velocities were significantly higher for pellets produced on T. weissflogii (322 +- 169 m d**-1) and E. huxleyi (200 +- 93 m d**-1) than on Rhodomonas sp. (35 +- 29 m d**-1). Preservation of carbon was estimated to be approximately 10-fold higher in fecal pellets produced when T. longicornis was fed E. huxleyi or T. weissflogii rather than Rhodomonas sp. Our study directly demonstrates that ballast increases the sinking rate of freshly produced copepod fecal pellets but does not protect them from decomposition.

    Vertical distribution and abundance of small zooplankton from the James Cook cruise JC087 (2014)
    PANGAEA
    Details
    Publication Date: 2023-03-07
    Description: Zooplankton samples were collected daily at the PAP site, using a Multinet of the type Midi with 50 µm nets. 5 depth strata (1000-500, 500-300, 300-100, 100-50 and 50-0 m) were collected at each sampling. The samples were preserved in 2% borax bufferred formalin. Zooplankton were identified on a species / genus level including different life-stages and eggs; at least 400 individuals were counted for each sample. When present, 10 individuals of each species and life-stages (for copepods) were measured for their prosome or total length.

    Zooplankton carbon budget from Trondheim mesocosm experiment (2014)

    Details
    Publication Date: 2024-02-16
    Description: We measured respiration, egg production and fecal pellet production of five common copepod species, when fed on suspended or aggregated food from two mesocosm, + NP and + NPSi. We hypothetised that calanoid copepods (Temora longicornis, Acartia spp., Centropages spp.) would feed mainly on suspended food, and have low respiration and egestion rates when food was only available as aggregates, while harpacticoids and Oncaea spp. would mainly feed on aggregated food and have low metabolic rates when only suspended food was available. Copepods were collected from the lagoon, and adapted to experimental conditions for 24 h. Food suspension was collected from the mesocosms, and either offered to copepods directly (suspended food) or after rotating in a plankton wheel until most phytoplankton was aggregated together (aggregated food). After 24-h incubation we counted the produced eggs and pellets, and measured copepod respiration using microelectrodes.

    Description: Gut chlorophyll of Microsetella norvegica and Oncaea spp. was measured daily at the PAP site from 8th to 14th of June, 2013. Copepods were collected using a WP2 -type net with a mesh size of 50 µm. Immediately after, 40-70 adults and late copepodites of each species (with 2-3 replicate samples) were washed in filtered sea water, placed on CF/F filters and extracted in acetone. Chlorophyll-a on filters was analysed using standard methods.

    Description: Respiration of Microsetella norvegica was measured at PAP site during two days, using a UNISENSE microrespiration system and microelectrodes for O2. 10-20 starved Microsetella individuals were carefully placed into 2-ml respiration chambers in filtered sea water, and their respiration was measured for 20 min. The respiration rate was calculated based on the slope of the decrease in oxygen against time in the respiration chamber containing Microsetella, compared to the control where only filtered seawater was present. In total 18 measurements were conducted.

    Publication Date: 2024-02-16
    Description: Egg and pellet production of Calanus finmarchicus was measured at 6-h intervals at all stations during the second leg of the cruise. Calanus was collected at the surface 150-m using a WP2 plankton net, and incubated in chl-max water for 24-h. Each 6 hours females were transferred to a new food solution and eggs and pellets were counted. In the end of the experiment, females were measured for prosome length. The purpose of the exercise was to calculate the minimum carbon consumption of Calanus, and how large proportion of ingestion is egested as fast sinking fecal pellets, and when.

    Publication Date: 2024-02-16
    Description: Harpacticoid Microsetella norvegica was fed with 5 concentrations of aggregates, collected from the station 1 (experiment 1) or from station 2 (experiment 2). The aggregates at station 1 were of phytoplankton origin and consisted mainly of Phaeocystis sp. and radiolarians; aggregates at station 2 were detritus collected from deep Mocness tows. M. norvegica was starved in filtered sea water for 〉 12 h, after which it was incubated together with aggregates for 8 h. After the incubation, pellets were counted and Microsetella and remaining aggregates were counted and measured. Pellet production of M. norvegica reflects feeding so that when pellet production is plotted against aggregate concentration, a functional response can be obtained.
