This dataset contains near-surface measurements of oceanographic, meteorological and physical data collected in situ from two autonomous surface vehicles Saildrone 126 and 128 in the Bering Sea in 2015 and 2016. The 2015 experiment took place between 2015-04-26 and 2015-07-28 and the 2016 experiment took place between 2016-05-23 and 2016-09-03. Saildrone is an unmanned autonomous sailboat powered by wind and solar energy. Under the umbrella of a Cooperative Research and Development Agreement (CRADA) between NOAA’s Pacific Marine Environmental Laboratory and Saildrone LLC, these vehicles were deployed on experimental missions in 2015 and 2016 to assess the viability of this observing platform. The major field program in FY15 and 16 was the test deployment of two saildrones which followed ice retreat in the Bering Sea, sailing from Dutch Harbor to Nome. Both saildrones had a variety of sensors and instruments consisting of thermosalinograph, ADCP, echo sounder, oxygen optode, fluorometer, SST IR pyrometer, anemometer, meteorological probe, digital barometer, and magnetometer. The oceanographic measurements include skin temperature, salinity, water temperature, water skin temperature, ocean currents, chlorophyll-a, CDOM concentration, red backscatter, fish biomass and dissolved oxygen. The atmospheric measurements consist of wind speed and direction, air temperature, relative humidity and air pressure. The physical measurements include tide direction and speed, magnetic field and water depth. All the data are in netCDF-CF (underway) format. These data are experimental and have not been quality controlled. There are known issues (offsets) in the sea surface salinity data and there might be unknown issues in other data variables. Users need to do quality control when using these data. These data are made available at the users own risk. The dataset will be updated as data are quality controlled and updated data become available.

This dataset is a hydrographic and atmospheric survey collected by sensors mounted on the Uncrewed Surface Vehicle Saildrone 1023 (SD1023) during the Circumnavigation of Antarctica in 2019. This Saildrone was deployed among two others (SD1020, SD1022) from southern New Zealand in austral fall 2019. These data include atmospheric measurements of barometric pressure, air temperature, PAR, wind speed and gust at height of 3.6m and 3.8m, respectively. These data include hydrographic measurements of sea surface temperature, relative humidity, sea water salinity, oxygen concentration in sea water and Chlorophyll concentration at depth of 0.5m.

The aerial surveys of Whales data in this accession were collected from aircraft by Steve Tracey over the Bering Sea between September 1987 and October 1988 by Sea World Research Institute, San Diego, CA. The data were submitted by Ms. Karen M. McClune in a tape. The data have been processed and are available in F127-Marine-Animal-Sightings file format of NODC.

The Conductivity, Temperature and Depth (CTD) and other data were collected in NW Pacific (limit-180), NE Pacific (limit-180), Greenland Sea and Bering Sea as part of Fisheries-Oceanography Coordinated Investigations (FOCI). Data was collected from NOAA Ship MILLER FREEMAN. The data was collected over a period spanning from April 4, 1992 to September 25, 1992. Data from 197 casts was submitted in one tape by Ms. Leslie Lawrence. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1 m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t) and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals.
