  <abstract><para>This data is part of the study NPRB Project 1012 &quot;Sea otter recolonization and interactions with commercially important macroinvertebrates in southeast Alaska&quot;. This is a MS Excel dataset. The data consists of observations made of foraging sea otters and samples taken from selected sea otter prey species.  We conducted foraging observations of tagged sea otters in previously unoccupied habitat, to determine the contirbution to the diet, near Kake.  Kake is currently undergoing an immigration of sea otters, and the prey species that otters target may shift as they enter previously unoccupied habitat. Observers used questar field spotting scopes and binoculars to identify prey. Location is noted as the observed coordinates of the foraging sea otter observed. Date, local time, dive duration, success, prey type, prey size, prey number, handling time and surface time are all recorded. The time interval includes 2010-2012.</para>

<methods><methodStep><description><section><title>Sea otter forage observations</title>

<para>Experienced observers made detailed observations on marked or unmarked foraging sea otters,within 750 meters of terrestrial vantage points. Using binoculars, Questar spotting scopes and stopwatches, the observers followed single otters through successive dives. They recorded the apparent sex and age of the focal otter, the start and end time of observations, as well as dive times, surface intervals, foraging success and the type, number and size of prey captured. Handling time for prey consumption and portion lost if any was also recorded.</para>

<methodStep><description><section><title>Prey sampling</title>

<para>When available prey were hand selected from the intertidal or subtidal using SCUBA from our study site. Between 10-34 prey invidivuals of each species or taxonomic class were sampled and processed. The processing removed unedible portions of the specimein (e.g. clam shells, urchin spines) that sea otter do not consume. Each prey sample was weighed to the nearest 1/10th of a gram and recorded. When sea otter prey species could not be collected from our study site, samples where obtained from collaborators from Glacier Bay, Alaska.</para>
