The data were collected by Flow Industries, Inc., under contract number 03-78-B01-61, "The Transport and Behavior of Oil Spilled In and Under Sea Ice", to NOAA. The data are primarily from drifting ice buoys and were collected in the Chukchi Sea, NW Coast of Alaska during the period December 19, 1981 to January 1, 1982 from six drifting buoys as part of Flow Project Icespil III. Three of the buoys have current and/or pressure records. Data has been processed to the NODC standard Drifting Buoy Data (F156) format. The F156 data type contains time series ocean circulation data determined by tracking the movement of drifting buoys, drogues or other instrumented devices. Movement is reported as point-to-point geographic locations determined by shore-based, surface ship, aircraft or satellite observations. Data from both ocean currents and sea ice movement can be reported in this format over time periods ranging from minutes to months. Directions and speeds between individual observations may be computed from these data and presented in graphic or summary listing form to provide information on circulation patterns and mass transport in offshore and nearshore regions. Platform name (for platform acquiring data or deploying device), drogue characteristics, start and end positions and times, and observation frequency (if constant time interval) are reported for each series of observations. The data record comprises position, date and time for each observation. Other surface meteorological or oceanographic parameters (e.g., water temperature and salinity, air temperature and pressure, wind, waves) and subsurface data (depth, pressure, temperature) may also be reported. Text records may be used to report general comments or to describe individual drogue observations.

This data set was collected as part of the Joint Monitoring Program during seismic activities in the Chukchi Sea. The 2006 data was collected by ship and aircraft as part of the Joint Monitoring Program during seismic activities in the Chukchi Sea in summer and fall of 2006. The 2007 data was collected by ship as part of the Marine Mammal Monitoring and Mitigation During Open Water Seismic Exploration program in summer and fall of 2007. The objective of the surveys was to update data on distribution and relative abundance of marine mammals in coastal areas of the eastern Chukchi Sea during the open-water season.

Bering Strait Mooring Cruise Underway Data 2022 This is an archive of underway data from the Bering Strait mooring cruise on the research vessel Norseman II, from Nome to Nome, 8th-19th September 2022. The cruise collected 3 types of underway data: meteorological (including wind velocity, air temperature and pressure and relative humidity); thermosalinograph (temperature and conductivity); and vessel-mounted ADCP (with bottom tracking). For full parameter list, see data file headers. To avoid sediment clogging of the thermosalinograph, that system was turned off while the ship was in Port Clarence during a large storm (~16-18 September 2022).

The Conductivity, Temperature and Depth (CTD) and other data were collected in Chukchi Sea. Data was collected from Ship ALPHA HELIX. The data was collected over a period spanning from September 21, 1992 and October 4, 1992. Data from 107 casts was submitted in one diskette by Dr. Chirk Chu of Institute of Marine Science, University of Alaska, Fairbanks, AK. 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.

A 35-day NSF-sponsored cruise aboard the USCGC Polar Star has studied in depth the physical oceanography of the Chukchi Borderland and Mendeleev Ridge regions. An extensive hydrographic survey (126 CTD casts) was conducted. In addition to CTD profiles of temperature, conductivity, oxygen, and light scatter and L-ADCP profiles of water velocity, bottle samples were taken for nutrients (2662 samples), dissolved oxygen (2999 samples), salinity (3066 samples) and tracers CFCs (F11, F12, F113, ca. 2500 samples), O18 isotopes (ca.1000 samples), Barium (ca.1000 samples), Helium (ca.108 samples), Iodine-129 (96 samples) and Cesium-137 (27 samples). Twenty-one denitrification (N:Ar ratio) samples were also taken. A total of 47 XBTs were used both to increase spatial coverage over the shelf and to increase spatial resolution in the slope regions. To better map the boundary current regime, 3 oceanographic moorings carrying current meters and temperature and salinity sensors were deployed across the boundary current for the ca. 1 month duration of the cruise. During the cruise, via a website of daily updates from a High School teacher aboard the Polar Star and visits to schools in Barrow, we brought Arctic research into the classroom. Post-cruise a multi-institute team of scientists will study this extensive data set, with reference to previous (sparse) measurements, Canadian measurements taken this year in the Canadian Basin and near Northwind Ridge, and modeling results, to understand the role of this Arctic Crossroads in the circulation of the Arctic Ocean.

Thirteen moorings sites throughout the northeastern Chukchi Sea shelf were occupied in various combinations for eight field years, 2008-2016. Two separate taut line moorings were deployed at most sites. The primary mooring employed at all sites deployed a Teledyne RDI Acoustic Doppler Current Profiler (ADCP) to measure water and sea ice velocities. Except at the locations over Hanna Shoals, 2011-2012, a second mooring deployed an Ice Profiling Sonar (IPS) instrument, manufactured by ASL Environmental Sciences Inc. (ASL), to measure ice keel depths and wave diagnostics, and a Sea Bird Electronics 37-SM CT sensor to measure water temperature and conductivity (and thus derive salinity). Moorings were deployed during the ice-free season, then recovered and redeployed in subsequent years. Data at the Crackerjack mooring location was collected until 2016 because though recovery was intended for 2015, weather delayed it until the next year. Data collection was conducted by Olgoonik Fairweather LLC (Fairweather) of Anchorage, Alaska, and ASL, Victoria, B.C., Canada. Fairweather provided logistical support to ASL field personnel during oceanographic mooring recovery and redeployment, and ASL was contracted to collect and analyze data. UAF processing was limited to assembling the data into this data submission. NCEI received the data in text and MS Excel formats. The latter have been exported to CSV text.
