Carbon export (from the epipelagic towards the mesopelagic zone) and sequestration (from the mesopelagic towards the bathypelagic zone) in the ocean are reviewed. Particulate organic carbon (POC) flux, and active flux due to migrant zooplankton and micronekton are shown from the epipelagic to the mesopelagic zone, and from the latter to the bathypelagic zone. Values towards the meso- and bathypelagic zones are compared in oligotrophic and productive systems. Zooplankton and prokaryote respiration in the meso- and bathypelagic zones of the ocean are also reviewed for oligotrophic and productive systems. Values were integrated over a depth layer and are given as the flux or respiration under one square meter (in g/m**2/a) between e.g. 100 m and 1000 m depth.Citation

Integrated daytime EK60 echosounder data from Malaspina-2010 cruise(PANGAEA - Data Publisher for Earth & Environmental Science, 2020) [Dataset]Daytime acoustic data (nautical area scattering coefficients, in m2/nmi2) integrated over 2 m vertical bins, from 200 to 1000 m depth. Data in each “pixel” is the average of all cleaned and valid data recorded at that depth range, in a time period starting 8 hours before the start of a station (defined as start of the CTD cast) and ending 8 hours after the start of the station, subject to being in the period between 1 hour after local sunrise and 1 hour prior to local sunset (i.e. during local daytime hours, but removing crepuscular periods). The relatively long interval over which data was accepted around each station was chosen due to frequent occurrences of periods of unusable acoustic data. Note that the provided positions correspond to the fixed Malapina station at that date, not the start and end point of the data collection.

Primary production using ¹⁴C method in subtropical gyres regions, supplement to: Regaudie-de-Gioux, Aurore; Huete-Ortega, Maria; Sobrino, Cristina; López-Sandoval, Daffne C; González, N; Fernández Carrera, Ana; Vidal, Montserrat; Marañón, Emilio; Cermeño, Pedro; Latasa, Mikel; Agustí, Susana; Duarte, Carlos Manuel (2019): Multi-model remote sensing assessment of primary production in the subtropical gyres. Journal of Marine Systems, 196, 97-106(PANGAEA - Data Publisher for Earth & Environmental Science, 2019) [Dataset]Seawater was sampled from five depths in the euphotic zone corresponding to 100 % (ca. 3 m depth), 50 %, 20 %, 7 % and 1 % of incident Photosynthetically Active Radiation (PAR). For each depth, four 72 mL polystyrene bottles (three clear bottles and one dark bottle) were filled with unfiltered seawater, inoculated with 10 - 20 µCi NaH¹⁴CO₃ and incubated on-deck from dawn to dusk. Temperature and irradiance in the incubators simulated the water temperature and the incident irradiance at the corresponding depth of each sample by using a combination of neutral density and blue filters (Mist Blue, ref. 061, Lee Filters ®). After incubation, samples from three of the five depths (100 %, 20 % and 1 % PAR) were sequentially filtered through 20, 2 and 0.2 µm polycarbonate filters while the other depths (50 % and 7 % PAR) were directly filtered by 0.2 µm. Immediately after filtering, filters were then exposed to concentrated HCl fumes at least 12 h to remove the non-fixed inorganic ¹⁴C. Filters were placed in scintillation vials to which 5 mL of liquid scintillation cocktail was added. The radioactivity on each filter (disintegrations per minute, DPM) was determined using a Wallac scintillation counter. To compute the rate of photosynthetic carbon fixation, the dark-bottle DPM was subtracted from the light-bottle DPM values. A constant value of 24,720 µg L-1 (or 2,060 µmol L-1) was assumed for the concentration of dissolved inorganic carbon for surface waters in tropical ocean (Key et al., 2004). A correction factor of 1.05 was applied to this constant value for discrimination isotopic. Total primary production was calculated as the sum of the primary production on each size class.
