Stabilization of the Yaquina Bay shoreline along the northeastern edge of the Hatfield Marine Science Center (HMSC) campus in Newport, Oregon became necessary to halt erosion that threatened both HMSC critical infrastructure (seawater storage tank) and public access to the HMSC Nature Trail. A Dynamic Revetment (gravel beach) was installed...
This resolution is a tribute to the accomplishments and memory of Dr. Lavern J. Weber, first resident director of the Hatfield Marine Science Center. The House bill was subsequently adopted by the Oregon Senate.
A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap...
We evaluated how the use of bait as a fish attractant influenced the species and size composition 20 of demersal fishes viewed with a stereo video lander, at 160 sampling sites at Stonewall Bank, a 21 deepwater rocky reef complex in Oregon waters. We also studied the effectiveness of stereo...
This is a description of the physical setting and distribution of plant and animal species near the mouth of the Salmon River. Intertidal invertebrates are emphasized. A more marine location is contrasted with a more estuarine site.
The report was produced as an accompaniment to a special exhibition at the Baranov Museum titled "Whaling the Kodiak Grounds." The log book summarized here was found in 1964 by Fred Ogden and later donated to the Museum. Most of the records of the American Pacific Whaling Company are housed...
Superpopulation capture–recapture models are useful for estimating the abundance of long-lived, migratory species because they are able to account for the fluid nature of annual residency at migratory destinations. Here we extend the superpopulation POPAN model to explicitly account for heterogeneity in capture probability linked to reproductive cycles (POPAN-τ). This...
Similarly structured food web models of four coastal ecosystems (Northern California Current, Central Gulf of Alaska, Georges Bank, southwestern Antarctic Peninsula) were used to investigate competition among whales, fishes, pinnipeds, and humans. Two analysis strategies simulated the effects of historic baleen and odontocete whale abundances across all trophic levels: food...
Authors listed on this Accepted Manuscript vary slightly from those listed on the Version of Record. Harold L. Gibson is an additional author on the published version.
We examined the genetic structure of double-crested cormorants (Phalacrocorax auritus) across their range in the United States and Canada. Sequences of the mitochondrial control region were analyzed for 248 cormorants from 23 breeding sites. Variation was also examined at eight microsatellite loci for 409 cormorants from the same sites. The...
