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.

The Conductivity, Temperature and Depth (CTD) and other data were collected from 73 stations in Chukchi Sea and East Siberian Sea area. The station numbers are 1-6, 8-30, 32-74, 76. Data was collected from Ship ALPHA HELIX cruise HX189. The data was collected BY Dr. J. Grebmeier of the University of Tennessee over a period spanning from August 24, 1995 to September 1, 1995. This project was funded by Office of Naval Research under grant no: NAVY N00014-94-1-1042Grebmeier. Data in NODC file format F022 was submitted by Dr. Chirk Chu, Institute of Marine Science, University of Alaska, Fairbanks.

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.

From August 2010 – September 2012, six moorings (BC1 inshore to BC6 offshore), spaced ~13 km apart, spanned the head of Barrow Canyon, Chukchi Sea, Alaska. Each mooring contained an upward looking 300 or 600 kHz Teledyne ADCP and a temperature/conductivity/pressure (T/C/P) recorder (Seabird SBE-37 or SBE-19). Moorings BC-2 through BC-5 included bottom tracking for measuring ice keel depths and ice drift. Bottom-tracking was inactive on BC-1 and BC-6 because these included directional wave firmware. The T/C/P and ADCP were housed in a float situated ~4 m above bottom. BC1, the mooring nearest to the coast, was deployed in a water depth of 31 m with its instruments mounted 1-m above the bottom in a SeaSpider frame. The compact mooring design minimized damage from nearshore ice keels that can exceed 25 m depth. After recovering the array in 2012, we deployed a single mooring (BC2) in 3 succeeding years.

This dataset includes a reference baseline used by the Digital Shoreline Analysis System (DSAS) to calculate rate-of-change statistics for the exposed north coast of Alaska coastal region between Point Barrow and Icy Cape for the time period 1947 to 2012. This baseline layer serves as the starting point for all transects cast by the DSAS application and can be used to establish measurement points used to calculate shoreline-change rates.

The Conductivity, Temperature and Depth (CTD) and other data were collected in Gulf of Alaska, Chukchi Sea, and NW Pacific (limit-180). Data was collected from cruises HX 161, HX 163, HX 165 and HX 167 of R/V ALPHA HELIX. The data was collected over a period spanning from March 16, 1992 to October 27, 1992. Data was submitted in one exabyte cassette by Dr. Thomas C. Royer, Institute of Marine Science, University of Alaska, Fairbanks, AK. CTD data is available in F022-CTD-Hi Resolution file format of NODC. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-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 1m. 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 text record is available for comments.

This collection includes temperature, salinity, oxygen, and fluorescence profile data from Alpha Helix cruises as well as current meter resultant, water temperature, and salinity time series data collected from moored buoys. The data were collected in the Chukchi Sea and the Gulf of Alaska as part of the Circulation of the North Central Chukchi Sea Shelf project from 1991-09-29 to 1996-09-03. The data were collected by the Institute of Marine Science, University of Alaska, Fairbanks, and was submitted by Dr. Thomas Weingartner.
