This data collection includes data from multiple SVP drifters deployed in the region of American Samoa to assess ocean currents and sea surface temperature. Drifter data files contain drifter ids, year, month, day, hour, minute, second, GPS latitude and longitude. Drifter data was collected hourly. All dates and times are UTC. Contact Coral Reef Ecosystem Division (CRED), NOAA Pacific Island Fisheries Science Center for more information. These data were collected for coral reef ecosystem research. They are collected concurrently with ecological/biological reef assessments and monitoring data.

Data has been processed by NODC to the NODC standard Ocean Drifter (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.%BR%%BR%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.

Drifters were deployed from vessels in the Chukchi Sea during the ice-free seasons of 2011-2013. Drifter positions were determined via GPS, and positions were relayed via Iridium communications to on-shore data centers. Drifters were tracked from their release until they a) were picked up at sea for redeployment; b) beached on-shore; or c) died at sea because of battery failure or other causes. Many drifters remained active as sea ice re-formed in the region, and 3 drifters were frozen in the ice and released the following spring. Drifters also recorded Sea Surface Temperature (SST) from 2012 onward. Drifters were of various types (Davis, SVP, and Microstar) and were drogued at various depths (1 m and 10 m).

The drifting buoy data in this accession was collected from 120 stations over 15 year period by US Coast Guard, Groton, CT. The data was collected between April 5, 1976 and October 16, 1991. This 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.

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. The water depth and other drifting bouy data submitted by Mr. Don Murphy has been processed by NODC and is currently available in F156 Drifting Buoy file format.
