  • Southcentral Alaska Stock
    Revised: April 2014 NORTHERN SEA OTTER (Enhydra lutris kenyoni): Southcentral Alaska Stock STOCK DEFINITION AND GEOGRAPHIC RANGE Sea otters occur in nearshore coastal waters of the U.S. along the North Pacific Rim from the Aleutian Islands to California. The species is most commonly observed within the 40-meter (approximately 12.2 feet [ft]) depth contour because the animals require frequent access to benthic foraging habitat in subtidal and intertidal zones (Reidman and Estes 1990). Sea otters are not migratory and generally do not disperse over long distances, although movements of tens of kilometers (km) (tens of miles [mi]) are common (Garshelis and Garshelis 1984). Annual home range sizes of adult sea otters are relatively small, with male territories ranging from 4 to 11 square kilometers (km2) (approximately 10.5 to 28.5 square miles[mi2]) and adult female home ranges from a few to 24 km2 (approximately 62 mi2) (Garshelis and Garshelis 1984; Ralls et al. 1988; Jameson 1989). Due to their benthic foraging, sea otter distribution is largely limited by their ability to dive to the sea floor (Bodkin et al. 2004). 1 Figure 1. Approximate distribution and stock boundaries of northern sea otters in Alaska waters (shaded area). The spatial scale at which sea otter populations are managed remains an important, although largely unexplored issue (Bodkin and Ballachey 2010) deserving further study. Bodkin and Ballachey (2010) used models of sea otter mortality to show that range-wide reductions and extirpations during the commercial fur trade of the 18th and 19th centuries occurred not simply because of excessive harvest, but because the harvest was not allocated proportional to the abundance and distribution of sea otters.

  • Historically Active Volcanoes of Alaska Reference Deck Activity Icons a Note on Assigning Volcanoes to Cards References
    HISTORICALLY ACTIVE VOLCANOES OF ALASKA REFERENCE DECK Cameron, C.E., Hendricks, K.A., and Nye, C.J. IC 59 v.2 is an unusual publication; it is in the format of playing cards! Each full-color card provides the location and photo of a historically active volcano and up to four icons describing its historical activity. The icons represent characteristics of the volcano, such as a documented eruption, fumaroles, deformation, or earthquake swarms; a legend card is provided. The IC 59 playing card deck was originally released in 2009 when AVO staff noticed the amusing coincidence of exactly 52 historically active volcanoes in Alaska. Since 2009, we’ve observed previously undocumented persistent, hot fumaroles at Tana and Herbert volcanoes. Luckily, with a little help from the jokers, we can still fit all of the historically active volcanoes in Alaska on a single card deck. We hope our users have fun while learning about Alaska’s active volcanoes. To purchase: http://doi.org/10.14509/29738 The 54* volcanoes displayed on these playing cards meet at least one of the criteria since 1700 CE (Cameron and Schaefer, 2016). These are illustrated by the icons below. *Gilbert’s fumaroles have not been observed in recent years and Gilbert may be removed from future versions of this list. In 2014 and 2015, fieldwork at Tana and Herbert revealed the presence of high-temperature fumaroles (C. Neal and K. Nicolaysen, personal commu- nication, 2016). Although we do not have decades of observation at Tana or Herbert, they have been added to the historically active list.
