    In:  Supplement to: Fiedler, Björn; Fietzek, Peer; Vieira, Nuno; Silva, Pericles; Bittig, Henry; Körtzinger, Arne (2013): In Situ CO2 and O2 Measurements on a Profiling Float. Journal of Atmospheric and Oceanic Technology, 30(1), 112-126, https://doi.org/10.1175/JTECH-D-12-00043.1

    Description: In recent years, profiling floats, which form the basis of the successful international Argo observatory, are also being considered as platforms for marine biogeochemical research. This study showcases the utility of floats as a novel tool for combined gas measurements of CO2 partial pressure (pCO2) and O2. These float prototypes were equipped with a small-sized and submersible pCO2 sensor and an optode O2 sensor for highresolution measurements in the surface ocean layer. Four consecutive deployments were carried out during November 2010 and June 2011 near the Cape Verde Ocean Observatory (CVOO) in the eastern tropical North Atlantic. The profiling float performed upcasts every 31 h while measuring pCO2, O2, salinity, temperature, and hydrostatic pressure in the upper 200 m of the water column. To maintain accuracy, regular pCO2 sensor zeroings at depth and surface, as well as optode measurements in air, were performed for each profile. Through the application of data processing procedures (e.g., time-lag correction), accuracies of floatborne pCO2 measurements were greatly improved (10-15 µatm for the water column and 5 µatm for surface measurements). O2 measurements yielded an accuracy of 2 µmol/kg. First results of this pilot study show the possibility of using profiling floats as a platform for detailed and unattended observations of the marine carbon and oxygen cycle dynamics.

    Description: This dataset compiles all available ship-based biogeochemical measurements at the Cape Verde Ocean Observatory (CVOO) into one merged dataset. The irregular measurements at CVOO started in 2006 and are still ongoing aiming at increasing data coverage in a key region for air-sea interaction. The station has a bottom depth of 3600 m and lies in the center of the Cape Verde Fontal Zone, resulting in large variations of the present oligotrophic water masses as well as an oxygen-poor layer between 400 m to 500 m. The dataset includes oxygen, nutrients, dissolved inorganic carbon, total alkalinity, and particulate organic matter measurements, and ancillary ctd-data are also included. The research vessels used and the exact measurement methods as well as the laboratories varied on a cruise-to-cruise basis, accordingly the data has undergone additional quality-control checks. The checks included flier detection (WOCE-flagging) and crossover-analysis that resulted in bias corrections.

    Description: The video that was collected in November and December 2015 during horizontal transects with the PELAGIOS towed camera system during cruise MSM49 in waters around Cabo Verde in the eastern tropical north Atlantic was annotated using the video and annotation reference system (VARS) developed by the Monterey Bay Aquarium Research Institute. In total more than 40 hours of video were collected and annotated, and 43 taxonomic groups were annotated, mostly consisting of gelatinous zooplankton. This resulted in a dataset of diversity and abundance data from which vertical distribution, abundance and diversity of pelagic fauna could be derived (https://doi.pangaea.de/10.1594/PANGAEA.919333). This dataset provides examples of images of annotated organisms.

    Description: Pelagic observations were collected via horizontal video transects using the pelagic in situ observation system PELAGIOS from 50-1000 m during MSM49. The collected video was annotated using the video and annotation reference system (VARS) developed by the Monterey Bay Aquarium Research Institute. In total more than 40 hours of video were collected and annotated, and 43 taxonomic groups were annotated, mostly consisting of gelatinous zooplankton. The data consists of counts of taxonomic groups (〉1 cm) linked to location and depth in the Cape Verde region. These counts are converted to abundance data (ind./m3).
