Investigating the Role of Dune Grasses, Carbon Storage, and Marine Nutrient Subsidies to the Functions and Services of U.S. Central Atlantic Coastal Dune Ecosystems

Creator:

Jay, Katya R.

Abstract:

Sandy beaches and dunes cover approximately one-third of the world’s ice-free coastlines and provide ecosystem services including coastal protection, recreation, wildlife habitat, and carbon sequestration. These dynamic interface habitats are variably shaped by wind, waves, sedimentary processes, and vegetation feedbacks. Positive biophysical feedbacks lead to the formation of vegetated coastal...

The effects of thermodynamic parameterizations, ice shelf geometry, and tides on modeled basal melting of Weddell Sea ice shelves

Creator:

Mueller, Rachael D.

Abstract:

Antarctic Ice Sheet mass balance and, hence, sea level change is affected by the floating extensions of outlet glaciers and ice streams that take up about 44% of the coastline (Drewry et al., 1982) and are referred to as "ice shelves". Ice sheet mass loss accelerates when these ice shelves...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:

Biel, Reuben G.

Abstract:

Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

Submarine earthquakes, volcanic eruptions and ambient noise in the Northeast Pacific

Creator:

Haxel, Joseph H.

Abstract:

Passive hydrophone technologies and a variety of acoustic methods are applied in the deep-ocean and shallow water coastal environments of the northeast Pacific. A catalog derived from U.S. Navy regional hydrophone array recordings of acoustic T- phases from seafloor earthquakes is examined, describing space/time patterns through empirical orthogonal function analysis...

The Response and Effect of Emergent Coastal Vegetation to Sedimentation and the Distribution of Coastal Vegetation Communities along Environmental Gradients

Creator:

Lemein, Todd

Abstract:

Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...

On the nearshore impact of wave energy converter arrays

Creator:

O'Dea, Annika Magnuson

Abstract:

Radiation stresses, defined as the excess flow of momentum due to the presence of waves (Longuet-Higgins, 1964), are the main drivers behind the cross-shore and longshore forcing that results in wave setup, set-down, and longshore currents (e.g. Svendsen, 2006). Longshore currents entrain and transport sediment and therefore play an important...

Stratigraphic correlation of seismoturbidites and the integration of sediment cores with 3.5 kHz chirp subbottom data in southern Cascadia

Creator:

Black, Bran

Abstract:

In order to evaluate the shallow stratigraphy along the southern Cascadia abyssal margin and northern California abyssal plain, CHIRP subbottom profiles capable of imaging individual turbidite beds in the upper tens of meters of the subsurface were collected. Reflectors imaged with the 3.5 kHz CHIRP subbottom data represent turbidite beds...

Coupled wave and surge modeling of Tillamook Bay, Oregon : extreme events and climate change impacts

Creator:

Cheng, Tiffany Kay

Abstract:

Estuaries represent the confluence of land and ocean environments and encompass a number of complex interactions amongst tides, winds, offshore waves and the riverine contributions, all of which contribute to total water levels (TWLs). The study of TWLs and the relative weight of its components can assist local communities in...

Carbon storage in U.S. Pacific Northwest coastal dunes : the role of invasive beachgrasses and sand supply

Creator:

Stepanek, John

Abstract:

As global atmospheric carbon emissions continue to rise, scientists and land managers are increasingly looking to natural ecosystems to sequester and store carbon to buffer the impacts of climate change. Despite their small geographic size, many coastal ecosystems such as salt marshes, seagrass meadows, and mangroves sequester large amounts of...

Extreme Wave Runup and Runup Variability on Beaches

Creator:

Li, Chuan

Abstract:

Wave runup is an important physical process that affects nearshore sediment transport, coastal erosion, and flooding. Large and unexpected runup events can also be dangerous to beach goers. Extreme runup statistics are essential parameters used in engineering design of marine structures and in coastal management. Although the study of runup...
