  • The sediment response of a dissipative beach to variations in wave climate

    Creator:
    Haxel, Joseph H.
    Abstract:
    Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

  • The Erosion of Siletz Spit, Oregon

    Creator:
    Rea, Campbell Cary
    Abstract:
    Siletz Bay is a drowned river valley filled with Holocene alluvial and estuarine sediments and is separated from the ocean by a sand spit 3.8 km in length. Since the area was settled by white man in the 1890's, the bay has apparently experienced rapid siltation, due to increased farming...

  • Mitigating Microplastics : Development and Evaluation of a Middle School Curriculum

    Creator:
    Kowalski, Marie
    Abstract:
    Microplastics, plastic marine debris less than 5 mm in size, is a threat to the health of our oceans. One important way to reduce microplastics in our oceans is to educate people about the issue, particularly future decision-makers. In this study, a middle school curriculum was developed using current scientific...

  • Coastal landslides in northern Oregon

    Creator:
    North, William Benjamin
    Abstract:
    Landsliding is a significant contributor to continuous erosion of the 150-mile northern Oregon coast. Direct loss of land to the sea by landslides occurs along 47 percent of the coast. The remaining 53 percent has minor shifting of sand along depositional areas such as spits and dunes. These minor movements...

  • Analysis of rip current embayments on the Oregon coast

    Creator:
    Dalon, Matthew M.
    Abstract:
    Understanding the past, present, and future behavior of our nation's shorelines is vital for sensible coastal management. Localized areas of erosion, termed "erosional hot spots", can shift the shoreline landward threatening coastal infrastructure (Kraus and Galgano, 2001; Stauble and Gravens, 2004; McNinch, 2004). One specific type of erosional hot spot...

  • Processes of sea-cliff erosion on the Oregon coast : from neotectonics to wave run-up

    Creator:
    Shih, Shyuer-ming
    Abstract:
    Sea-cliff erosion is a significant problem along the Oregon coast in that many communities have been built on terraces affected by bluff retreat. There is considerable coast-wide variability in the rates of cliff erosion. This variability is attributed in part to tectonic activity that is causing differential interseismic uplift along...

  • Diversity and similarity of benthic fauna off Oregon

    Creator:
    Stander, Jeffrey M.
    Abstract:
    Samples of benthic organisms off the coast of Oregon, taken from depths varying from 50 to 2900 meters, have been analyzed in terms of diversity at a given station, and similarity and ecological distance to other stations. Estimates of epifauna abundance were also made. In the analysis an important distinction...

  • Causes of death and pathological findings in marine mammals stranded along the Oregon coast

    Creator:
    Stroud, Richard K.
    Abstract:
    Fifty-seven stranded marine mammals representing seven species were examined over a period of three years. The primary cause of death along with contributing factors, incidental pathology and parasites is reported for each animal examined. Gunshot wounds directly or indirectly caused the death of 14 of 44 seals and sea lions...

  • Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

    Creator:
    D'Antonio, Carla Marie, 1956-
    Abstract:
    Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

    Creator:
    Day, Donald Stewart
    Abstract:
    The 36 samples collected with a 22-foot semi-balloon shrimp trawl at depths from 40 to 1,829 meters off the central coast of Oregon between July 1961 and June 1962 provided preliminary data on the distribution, species composition, and associations of benthic fishes with respect to depth and sediment type. Sixty-seven...
