In the past, classification systems for the analysis of morphodynamic variability have been developed in an attempt to understand large scale coastal behavior. The motivation behind the creation of these classification systems has been to provide...

A 50 m² pelagic trawl equipped with a codend opening-closing device was used to sample micronektonic fishes between 500 m and 1000 m. Horizontal tows were made at 500, 650, 800 and 1000 m. Twelve of 15 common species captured showed significant...

This thesis covers a wide area of the North Pacific Ocean, latitudinally from 10° to 55°N and longitudinally from Japan to the U.S. coast. With two longitudinal cruises as the main data sources and selected literature data sets as supplementary...

This paper deals with the bone structure of albacore, fin whale and deep-sea rat-tail. The major components of bone - ash, organic, fat and water content are expressed on a volumetric basis. It has been found that both rat-tail and whale bone...

The benthic amphipod Corophium salmonis was sampled seasonally from two sites (Desdemona Sands and Grays Bay) in the Columbia River estuary. Populations of C. salmonis at both sites were found to have a two generation per year life cycle, a spring...
