Scientists at the Auke Bay Laboratory have conducted marine debris surveys on select beaches in Alaska periodically since 1972. Some of the beaches previously sampled have been identified as marine debris hot spots due to their increased debris accumulation. At each location, multiple 1 km beach segments were sampled by people walking the beach and enumerating all anthropogenic marine debris found. The beach area surveyed was from the waters edge up to the base of the storm berm or log piles. Individual beach segments have been walked multiple times in the since 1972 allowing for a direct comparison with prior years. Sampling occurred in late spring and summer to test the hypothesis of change in marine debris sources due to increased summer boat traffic and the diminished occurrence and severity of storms.

This dataset is from a laboratory study that investigated the effect of temperature and tissue type on fatty acid signatures of Pacific cod and walleye pollock.

This dataset is from a field experiment that examined how juvenile flatfish distribution changed with worm tube heterogeneity, i.e. density and patchiness.

This dataset contains 2-boat tow, push net and scoop net catches from the Yukon River Delta for 2014

The Nutritional Ecology Laboratory maintains a database containing all of the biochemical data we collect. The database includes seasonal information regarding size, age, location, date, developmental stage, and maturity status of all the specimens we have examined. Samples range from phytoplankton to whales and seals. Depending on the objectives of specific studies, these data can be matched to measures of energy content, proximate, lipid class, and fatty acid composition.

This dataset is from laboratory experiments examining intercohort variation in thermal reaction norms of Pacific cod.

To study the effects of ocean acidification we examined the effects of ocean acidification on the embryo stages of the economically important southern Tanner crab, Chionoecetes bairdi. Ovigerous females were reared in one of 3 treatments: control (ambient pH ~8.1), pH 7.8, and pH 7.5 for 2 years. Embryos in year 1 were from oocytes developed in the field whereas embryos in year 2 were from oocytes developed under acidified conditions. Datasets associated with this study include Brooding Duration, Carbonate Chemistry, Embryo Morphology, and Embryo Stages. Embryo stages assessed monthly included detailed developmental stages from the prefuniculus formation through the prehatching stage. Embryo stages were not different among pH treatments. Embryo morphology included egg area, egg diameter, yolk area, yolk diameter, embryo area, eye area, and eye diameter. Each morphological characteristic varied according to pH treatment using a principal
component analysis.

This dataset is from a study that evaluates whether inter-annual variability in the depth distribution of juvenile northern rock sole on their nursery grounds around Kodiak Island, Alaska, is a response to changes in the availability of habitat created by polychaete tubes, principally Sabellides sibirica.
