A disaster for the Pisaster? Temperature effects on Ochre sea star larval development
(2019)Marine ecosystems are threatened by climate change. Sea surface temperatures are rising as a result of global warming, which may influence the larval development and survival rates of many species. Decreasing the quantity ... -
Disruptive Distribution in the Music Business, Part 1: An Historical Perspective
(University of Washington Department of Communication, 6/10/2011)The current digital disruption to music distribution, while extensive, is not without historical precedent. The introduction of the phonograph, radio broadcasting, and a combination of several recording and distribution ... -
Dissolved Inorganic Carbon and δ13C of the Hawaiian Ocean Time Series from 1990-2021
(2022)As humans continue to produce large amounts of CO2 via the burning of fossil fuels, the concentrations and isotopic signature of the ocean’s dissolved inorganic carbon (DIC) is changing. Utilization of DIC and its δ13C as ... -
Dissolved lignin within the waters of Barkley Sound, Vancouver Island, Canada
(2010-05)This study used dissolved lignin phase as a biomarker to determine the plant sources of terrestrial derived organic carbon that enters into the waters of Barkley Sound, Vancouver Island. No studies have been conducted on ... -
Dissolved oxygen within Glacier Bay: sources, deep basin values and comparison to other glacial fjords
(School of Oceanography, University of Washington, 2008-06-19)Dissolved oxygen was measured at many stations in Glacier Bay. The purpose was to isolate the source of deep water renewal in the bay, and also to add to datasets of oceanographic observations. Glacier Bay is shallow silled, ... -
Dissolved Pollutants in the Great Pacific Garbage Patch, December 2021
(2022)The intent of this study was to identify and quantify dissolved chemical pollutants in the Northeastern Pacific Ocean. Samples were taken along a transect from Hawaii to San Diego that passed through the southern edge ... -
Distribution and abundance of juvenile intertidal bivalves in the San Juan Islands, WA
(2011)Adult distribution of intertidal bivalve communities is dependent on larval success and juvenile survival. Finding and predicting juvenile presence is crucial to understanding the mechanisms determining adult abundance. ... -
Distribution and abundance of juvenile intertidal bivalves in the San Juan Islands, WA
(Friday Harbor Labs, 2011-05)Adult distribution of intertidal bivalve communities is dependent on larval success and juvenile survival. Finding and predicting juvenile presence is crucial to understanding the mechanisms determining adult abundance. ... -
Distribution and Abundance of Porpoises In the San Juan Channel: Effects of Bathymetry and Tides
(Friday Harbor Labratories, 2012-12)The San Juan Archipelago is a dynamic cluster of islands supporting seven species of cetaceans including the harbor and dall’s porpoises. Under recognized in the San Juan Archipelago conservation and better management of ... -
Distribution and Composition of Phytoplankton in San Juan Channel in Fall 2013
(Friday Harbor Laboratories, 2013-12)Phytoplankton are the base of the marine food web. They have a rapid cell growth and reproduction and can produce million of cell per liters of seawater. Phytoplankton account for 95% of primary production. In the San Juan ... -
Distribution and dynamics of shell-‐boring Polydora on Crassostrea gigas
(2011)The proportion of live Crassostrea gigas infected with Polydorid spionid worms was surveyed at several locations around San Juan Island. Thirty infected C. gigas were collected from the Argyle ... -

(Friday Harbor Labs, 2011-05)The proportion of live Crassostrea gigas infected with Polydorid spionid worms was surveyed at several locations around San Juan Island. Thirty infected C. gigas were collected from the Argyle Lagoon locations and worm ... -
Distribution and Variation between Populations of Pacific Sand Lance in the San Juan Archipelago
(Friday Harbor Labs, 2012-12)In the San Juan Islands, the immediate trophic levels of the marine food web represent a critical link that is largely constituted by forage fish, including the Pacific Sand Lance. This document contains the results of an ... -
The distribution of bioavailable copper in Puget Sound surface waters
(2019)Surface water samples were collected from distinct locations throughout Puget Sound and from the Lake Washington-Lake Union-ship canal area. Samples were analyzed using ICP-MS and CLE/AdCSV for particulate copper, dissolved ... -
Distribution of microbial eukaryotes living as epibiota on tube worms (Ridgeia piscesae) in hydrothermal fluid flow and vent plumes at Axial Seamount
(2023-06)Hydrothermal vents are deep-sea environments characterized by high temperature, low pH, low oxygen concentration and high chemical concentrations with a chemosynthesis based ecosystem. Microbial eukaryotes (protists) ... -
The distribution of particulate organic carbon and sediment in the Elwha River dispersal system during the dam removal process
(2012)The delivery and deposition of particulate organic carbon (POC) into the marine environment via rivers impacts local biological and geological processes as well as the global carbon cycle. This is especially the case in ... -
