Abstract

Features in this feature class represent animal sightings that occurred during four aerial surveys for marine mammals performed in July 2014, September 2014, January 2015 and April 2015 in the Puget Sound, WA. Surveys followed line-transect protocol and were designed to collect data for estimation of abundance and density of marine mammals. Survey dates were 21 to 27 July 2014, 14 to 21 September 2014, 5 to 12 January 2015 and 15 to 22 April 2015. Work was performed under HDR task order JP04 (IDIQ contract award N62470-10-D-3011, NAVFAC LANT).

Attributes

Overview

Attributes described below represent those in the original dataset provided by the provider.
Only minimum required attributes are visible and downlodable online. Other attributes may be obtained upon provider's permission unless otherwise noted below.

This section explains attributes included in the original dataset. OBIS-SEAMAP restricts the attributes available to the public to date/time, lat/lon and species names/counts only. Should you need other attributes described here, you are encouraged to contact the data provider.
