    Zooplankton abundance trends and patterns in Shelikof Strait, western Gulf of Alaska, USA, – Ratio-independent prey preferences by an estuarine mysid The effects of parasite exposure on mortality from aquatic contaminants, carbaryl and elevated salinity, in a freshwater crustacean. Volume transport estimates varied considerably. In October the southwest flow bifurcated, with part continuing along the Alaska Peninsula and the rest exiting the main channel to the south; in March all upper-layer flow followed the main channel. Shelikof Strait appears to be a system influenced by both density-driven and wind-driven effects.

The spring zooplankton community in the coastal, western Gulf of Alaska and Shelikof Strait is dominated by calanoid copepods, particularly Neocalanus plumchrus and N. flemingeri (hereafter, Neocalanus spp.), in terms of biomass, and Neocalanus spp., Metridia pacifica, Pseudocalanus spp., Oithona spp.

Walleye pollock egg resources constituted on average % of April and % of May copepod production in the Shelikof Strait marine food web. In addition, the resource contributions from eggs appear 1 to 3 wk earlier than the spring peak rates of zooplankton Zooplankton of Shelikof Strait and thus occur at a time when equivalent dietary resources are still.

Interestingly, larvae of several other species that co-occurred with walleye pollock in this cluster, Alaska plaice, Pacific cod, and gray starsnout, also demonstrate high abundances of larvae in Shelikof Strait and the Shelikof exit region (Matarese et al., ). This suggests that larvae in this cluster are particularly affected by.

Zooplankton components. Large zooplankton observations were made along the Seward Line using a 1-m 2 MOCNESS equipped with μm mesh nets as outlined in Coyle and Pinchuk,Coyle and Pinchuk, Afterlarge zooplankton were collected with a m 2 Hydrobios Multinet system equipped with μm mesh nets.

These data were obtained as part of an ongoing effort to describe the environment of the Shelikof Strait region of Alaska and File Type: [PDF - MB. Interannual copepod abundance (number m −3) and sea surface temperatures (SST, 2-m depth) were examined from four stations in Icy Strait, southeastern Alaska, monthly from May to September, – SST was generally lowest in May (≅7°C), increased rapidly to a summer peak (≅12°C), and declined again by September.

()) zooplankton during spring in Shelikof Strait, Alaska* Abstract.-Microzooplankton retained by a ~m mesh was sampled along a kIntransectin the Shelikof Strait between Kodiak Island and theAlaska Pen­ insula.

We sampled once each year during spring (April-May) ­ using Niskin bottles closed at mdepth intervals. Zooplankton was sampled in Shelikof Strait and some of the surrounding shelf waters from March to Octoberand then in Shelikof Strait during springusing and mum mesh nets.

Conditions affecting distributions of larval walleye pollock (Theragra chalcogramma) were examined at Shelikof Strait, Alaska, during springtime, and The winds within Shelikof Strait, Alaska, have been examined using hourly observations from a pair of meteorological buoys moored at the ends of the strait for a 6-month period in The focus is on periods of gap winds, when the prominent terrain bordering Shelikof Strait constrains the low-level winds to accelerate down the local pressure.
