Gulf Watch Alaska, Nearshore Monitoring Component:

Summary

This data is part of the Gulf Watch Alaska (GWA) long term monitoring program, benthic monitoring component and a seasonal diet study in Kenai Fjords National Park. The dataset is a comma separated file exported from a Microsoft Access database. The data consists of observations made of foraging sea otters (Enhydra lutris). Observers used Questar field model spotting scopes and binoculars to identify prey. Date, local time, dive duration, success, prey type, prey size, prey number, handling time and surface time are all recorded.

The purpose of this data is to allow comparison of a set of sea otter forage data metrics across time and geographic location. Metrics include: foraging success rate, composition of prey, mean size and/or size frequency distribution of common prey, number of prey items per dive, and rate of energetic return. Comparisons include metrics from one location over time or from one time across locations.
