Southern Elephant Seal as Oceanographic Samplers (SEaOS) -South Georgia

This dataset contains temperature and light CTD data from the Marine Mammals Exploring the Ocean Pole to Pole (MEOP) program taken TDR (time-depth recorder) deployed on elephant seals in Kerguelen Island area from 2008-10-17 to 2016-01-17. The Oceanographic data collected by Antarctic seals (Southern Elephant and Weddell seals mainly) are collected as part of the SO-MEMO (Observing System - Mammals as samplers of the Ocean Environment, PI. C. Guinet, CEBC-CNRS-ULR). Data were collected in combination with geo-positioning measurements. The loggers, either TDR-MK9 or TDR10, are manufactured by Wildlife Computers and are able to measure continuously pressure, temperature and light along the seal foraging trip. The resolution and precision of temperature data is rather low, of order 0.5C, however the spatial resolution is unusually high with more than 60 profiles every day. Data are in NetCDF.

This dataset is a large collection of temperature casts recorded by fast-response archival time-depth recorder tags on northern elephant seals during their natural migrations. Only ascents (upcasts) were retained to ensure a similar format to traditional ship-based casts. Each file represents data from a single instrument on one adult female elephant seal. Temperature and depth data were obtained from data logging tags manufactured by Wildlife Computers (MK9 or MK10). Temperature and depth values are uncorrected, raw instrument readings. The position of each cast was estimated using a state-space model smoothing algorithm applied to the ARGOS satellite track of the seal. Position data were obtained from a combination of GPS loggers and ARGOS PTT transmitters manufactured by Wildlife computers (SPOT4, SPOT5, or MK10) or the Sea Mammal Research Unit (SMRU SRDL)). Position data were irregular in time and contained substantial spatial error. So, we estimated a position for each station by smoothing the data using the CRAWL package in R-Cran and then applied a linear interpolation for each station.

Temperature and salinity data were collected by SeaCAT sensors from seven deployments within 2004-2007 on the HALE-ALOHA mooring, a location about 100 km north of Oahu, Hawaii, USA. The HALE-ALOHA mooring supports the Hawaii Ocean Time-series program. The SeaCAT sensors were one of many instruments deployed for the Multi-disciplinary Ocean Sensors for Environmental Analyses and Networks (MOSEAN) project, lead by the Ocean Physics Laboratory (OPL) of the University of California at Santa Barbara. The MOSEAN project is funded by the National Oceanographic Partnership Program (NOPP). The main goal of MOSEAN is to develop and test relatively small, lightweight optical and chemical sensors for autonomous deployment. Each deployment lasted around six months. The Seabird Electronics SeaCAT 16 provided 5-minute sampling and were mounted at various depths ranging from 10 to 200 m. Each deployment had one or two depths and depth levels varied among deployments. There were no available data for deployment 4. The data were quality controlled by the OPL.

Ocean City Buoy. Woods Hole Oceanographic Institution (WHOI) data from a local source.

Temperature and salinity CTD data from the Marine Mammals Exploring the Ocean Pole to Pole (MEOP) program. This dataset largely samples high northern and southern latitudes using instrumented (CTD) animals (elephant seals). There are several hundred thousand profiles in this data set which runs from 2004 to 2024. Data are in NetCDF. Downloaded from the MEOP database on 2024/08/12.
