AFSC/NMML Location-only satellite telemetry data for gray whales in the Bering and Chukchi Sea, 2012-2013

This dataset contains ARGOS location data (latitude and longitude in decimal format) and associated time (date and time) and location quality (as defined by Argos System, www.argos-system.org) information. Data were collected using Wildlife Computers PTT-only SPOT 5 and Archival Mk10A satellite transmitters and PTT identification is also provided with the data. Satellite transmitters were deployed on gray whales (Eschrichtius robustus) in the Chukchi Sea.

These data were collected to monitor movements of gray whales using satellite telemetry

The following FGDC sections are not currently supported in InPort, but were preserved and will be included in the FGDC export:

- Taxonomy (FGDC:taxonomy)

- Spatial Data Organization Information (FGDC:spdoinfo)

The dataset contains location data (latitude and longitude) of gray whales satellite tagged in the Chukchi sea in 2012 and 2013. The location data contains five columns labeled latitude, longitude, time.utc, ptt.id, lq. Details of the column contents are described under Detailed Descriptions of the metadata

Metadata Detailed Descriptions

The metadata contains location data for gray whales tagged with satellite transmitters between 2012 and 2013. Care should be taken to understand the elements in the metadata record and the distributor shall not be held liable for improper or incorrect use of the data. If assistance is needed, contact the distributor.

Data is available at NCEI: http://data.nodc.noaa.gov/cgi-bin/iso?id=gov.noaa.nodc:0139361

There are no legal restrictions on access to the data. They reside in public domain and can be freely distributed.

User must read and fully comprehend the metadata prior to use. Applications or inferences derived from the data should be carefully considered for accuracy. Acknowledgement of NOAA/NMFS/AFSC as the source from which these data were obtained in any publications and/or other representations of these data is suggested.

LQ Z and LQ removed by the argosfilter package were removed from the data. No duplicate features are present in the dataset

not provided

Attribute accuracy is provided in the Location Quality (LQ) field. The current dataset has 6 LQ levels. Tagging is the GPS location where a satelitte transmitter was deployed and has GPS precision. The accuracy of remaining LQ levels are as defined by Argos Service and are classified in different classes of decreasing accuracy in the following order: 3, 2, 1, 0, A, B, and Z. LQs 3, 2, 1, and 0 have estimated accuracies of 150, 350, 1,000, and greater than;1,000 m. LQs A, B, and Z have no estimated location accuracy. LC Z are points for which the location process failed and were not included in the present dataset.

IT Security and Contingency Plan for the system establishes procedures and applies to the functions, operations, and resources necessary to recover and restore data as hosted in the Western Regional Support Center in Seattle, Washington, following a disruption.
