Synthesis Of Shoreline, Sea Level Rise, And Marsh Migration Data For Wetland Restoration Targeting Final Report, Molly Mitchell, Karinna Nunez, Christine Tombleson, Julie Herman

Data

Coastal marsh loss is a significant issue globally, due in part to rising sea levels and high levels of coastal human activity. Marshes have natural mechanisms to allow them to adapt to rising sea levels, however, migration across the landscape is one of those mechanisms and is frequently in conflict with human use of the shoreline. Ensuring the persistence of marshes into the future requires an understanding of where marshes are likely to migrate under sea level rise and targeting those areas for conservation and preservation activities. The goal of this project was to 1) compile existing datasets and information …

Dataset: A Numerical Simulation Of The Ocean, Sea Ice And Ice Shelves In The Amundsen Sea (Antarctica) Over The Period 2006-2022 And Its Associated Code And Input Files, Pierre St-Laurent

Data

A three-dimensional numerical model of the Amundsen Sea (Antarctica) was used to simulate the period Jan.2006-Mar.2022 under consistent atmospheric/oceanic forcings, bathymetry/ice shelf topography, and model equations/parameters. The model is an implementation of the Regional Ocean Modeling System (ROMS, https://www.myroms.org/) with extensions for sea ice (Budgell 2005) and ice shelves (Dinniman et al. 2011). It simulates the ocean hydrography and circulation, sea ice thermodynamics and dynamics, and the basal melt of the ice shelves, with a uniform horizontal mesh of 1.5km and 20 topography-following vertical levels. Forcings include the ERA5 reanalysis (3-hourly), 10 tidal constituents from CATS 2008, and ocean/sea ice …

Dataset: Global Seamless Tidal Simulation Using A 3d Unstructured-Grid Model, Yinglong J. Zhang, Tomas Fernandez-Montblanc, William Pringle, Hao-Cheng Yu, Linlin Cui, Saeed Moghimi

Data

Dataset:

We present a new 3D unstructured-grid global ocean model to study both tidal and non-tidal processes, with a focus on the total water elevation. Unlike existing global ocean models, the new model resolves estuaries and rivers down to ~8m without the need for grid nesting. The model is validated with both satellite and in-situ observations for elevation, temperature and salinity. Tidal elevation solutions have a mean complex RMSE of 4.2 cm for M2 and 5.4 cm for all 5 major constituents in the deep ocean (the RMSEs for the other 4 constituents (S2, N2, K1, O1) are respectively: 2.05cm, …

The Middle Atlantic Outer Continental Shelf Environmental Studies: Data Files, Gary F. Anderson

Data

During the oil embargo in the mid-1970’s, the U.S. Government proposed exploring the mid-Atlantic continental shelf for oil leasing to increase production. The Virginia Institute of Marine Science was contracted by the Bureau of Land Management (BLM) to conduct baseline surveys of the biological, geological, chemical, and physical nature of the environment being considered for lease, and its sensitivity to prolonged exposure to contaminants derived from development activities. Surveys were conducted off the coast, from Virginia to New Jersey, four times a year (summer, fall, spring, winter) for two years beginning summer of 1975 through spring of 1977, resulting in …

Vims Ferry Pier Ambient Water Monitoring And Meteorological Data, Six-Minute Data 1986-2003, Gary F. Anderson

Data

Bulk water parameters of Temperature and Salinity were measured at the VIMS Ferry Pier from 1947 to 2003. Initial methods were undocumented but likely automated with an instrument and chart recorder since the data consists of a daily high and low measurement from which a mean value was derived. Beginning in 1986 an Inter-Ocean CTD instrument placed at mid-depth was interfaced to a digital data logger (Campbell Scientific CRJ) that recorded data every six minutes, resulting in 240 measurements per day.

This collection contains only the six-minute data from 1986 through 2003. Weather parameters were also added in 1986 and …

Associated Dataset: Impacts Of Atmospheric Nitrogen Deposition And Coastal Nitrogen Fluxes On Oxygen Concentrations In Chesapeake Bay, Fei Da, Marjorie A.M. Friedrichs, Pierre St-Laurent

Data

The dataset includes model outputs used in publication Da et al. (2018), which used the Estuarine-Carbon-Biogeochemistry model embedded in the Regional-Ocean-Modeling-System (ChesROMS-ECB) to examine the relative impact of direct atmospheric dissolved inorganic nitrogen (DIN) deposition and DIN from the continental shelf on the Chesapeake Bay dissolved oxygen. Model simulations highlight that DIN from the atmosphere has roughly the same impact on hypoxia as the same gram-for-gram change in riverine DIN loading. DIN concentrations on the continental shelf has a similar overall impact on hypoxia as DIN from the atmosphere.
