Oxygen is produced by phytoplankton photosynthesis and consumed by respiration of phytoplankton, zooplankton and bacteria. Oxygen also enters and exits the ocean via physical exchange with the atmosphere. Oxygen concentrations in the surface ocean may be supersaturated by photosynthesis and turbulence enhancing air-sea exchange via bubble injection; or undersaturated due to excess respiration. In cases where exchange with the atmosphere is limited, and/or respiration exceeds photosynthesis, oxygen concentration can be reduced to very low levels (hypoxia) or entirely depleted (anoxia). This is uncommon in cold Antarctic Seas where respiration is depressed and oxygen solubility is enhanced by low temperature. Different water masses have characteristic oxygen concentrations which serve as tracers for diagnosing physical mixing and advection. Dissolved oxygen was analyzed by Winkler Titration (see Methods) in Conductivity, Temperature, Depth (CTD)-Rosette bottle samples at all depths sampled until 2012. This measurement was discontinued in 2013. The CTD has duplicate oxygen electrodes that provide continuous vertical profiles of oxygen concentration at all depths on all casts. The vessel also has continuous underway, Optode determination of dissolved oxygen in the surface (ship's intake at 6 meters depth) on all cruises. Finally we now routinely measure net community production by Equilibrator Inlet Mass Spectroscopy (EIMS) on LTER cruises\n\ncdm_data_type = Trajectory\nVARIABLES:\nstudy_name (Study)\ntime (seconds since 1970-01-01T00:00:00Z)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (m)\nevent\ngrid_line\ngrid_station\nbottle\noxygen_concentration (mL L-1)\noxygen_concentration_moles (micromoles L-1)\ncomments\n | https://pallter-data.marine.rutgers.edu/erddap/metadata/fgdc/xml/CruiseDissolvedOxygen_fgdc.xml | https://pallter-data.marine.rutgers.edu/erddap/metadata/iso19115/xml/CruiseDissolvedOxygen_iso19115.xml | https://pallter-data.marine.rutgers.edu/erddap/info/CruiseDissolvedOxygen/index.htmlTable | https://pal.lternet.edu/![]() | http://pallter-data.marine.rutgers.edu/erddap/rss/CruiseDissolvedOxygen.rss | https://pallter-data.marine.rutgers.edu/erddap/subscriptions/add.html?datasetID=CruiseDissolvedOxygen&showErrors=false&email= | National Science Foundation | CruiseDissolvedOxygen | ||

We rely on signatures of naturally occurring carbon (13C/12C, δ13C) and nitrogen (15N/14N, δ15N) stable isotopes (SI) as integrated proxies of penguin trophic foraging and food-web structure. Each season, study nests, where pairs of adults were present, were individually marked and chosen before the onset of egg-laying, and consistently monitored. When study nests were found at the one-egg stage, both adults were captured to obtain blood samples used for molecular sexing and stable isotope analyses, and measurements of structural size and body mass. At the time of capture, each adult penguin was quickly blood sampled (~1 ml) from the brachial vein. After handling, individuals at study nests were further monitored to ensure the pair reached clutch completion, i.e., two eggs. At approximate an average nest age of five and 15 days, offspring from study nests were captured and quickly blood sampled (<= ~500 µl for day five chicks, and <= ~1 ml for day 15 chicks) from the tarsus vein using a sterile needle and heparinized capillary tubes for day five chicks, and a sterile 3 ml syringe and heparinized infusion needle for day 15 chicks, again to obtain blood tissue for SI analyses. Study nests were monitored for chick survival to 25 days. At five weeks into chick-rearing, older crèched chicks of all three species were captured and quickly blood sampled from study rookeries near Anvers Island. Handling of crèched chicks occurred over a one or two day period, which varied seasonally and by species depending on nest initiation dates.
