USGS CoastCam at Madeira Beach, Florida: Timestack Imagery and Coordinate Data

A digital video camera was installed at Madeira Beach, Florida (FL) and faced west along the beach. Every hour during daylight hours, daily from 2017 to 2022, the camera collected raw video and produced snapshots and time-averaged image products. One such product is a "runup timestack". Runup timestacks are images created by sampling a cross-shore array of pixels from an image through time as waves propagate towards and run up a beach. Runup timestacks store the red, green, and blue or monochrome pixel intensity as a function of the cross-shore position as imagery for the sampling period, typically around 17 minutes. The images included in this data release were collected from January 21, 2017, to January 25, 2022. The camera is part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. USGS researchers analyzed the timestack imagery collected from this camera to remotely sense information such as elevation of wave runup. This camera is part of the USGS CoastCam network, supported by the Total Water Level/Coastal Change Project under the Coastal and Marine Hazards and Resources Program (CMHRP).

Mobile Harbor Navigation Channel Delft3D Model Inputs and Results - With-Project Condition 2010 Simulation With 0.5-meter of Sea Level Rise

The numerical model Delft3D (developed by Deltares) was developed to evaluate the potential effects of proposed navigation channel deepening and widening in Mobile Harbor, Alabama (AL). The Delft3D model setup requires the input of a merged topographic and bathymetric elevations, a wave climate based on significant wave heights, peak wave period and mean wave direction, and a tidal-time series. The model was validated by comparing model outputs from deterministic runs with observations of water levels and velocities. The validated model was used to simulate scenarios of existing conditions and proposed with-project conditions (for example, channel deepening and widening). Simulations were performed for one year (the year 2010) and ten years, with and without 0.5 meters (m) of sea level rise. Model inputs and outputs in the form of topography and bathymetry for the scenario runs as well as output water levels and velocities for the deterministic runs are provided in this data release. For further information regarding model input generation and visualization of model output topography and bathymetry, refer to USGS Open-File Report 2018-1123.

Projected Seafloor Elevation Change and Relative Sea Level Rise Surrounding Maui, Hawaii 25, 50, 75, and 100 Years from 1999

The U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted research to quantify bathymetric changes surrounding Maui, Hawaii. Changes in seafloor elevation were calculated using historical bathymetric point data from the 1960s (see Yates and others, 2017a) and light detection and ranging (lidar)-derived data acquired in 1999 (NOAA, 2013) using methods outlined in Yate and others (2017b). An elevation change analysis between the 1960s and 1999 data was performed to quantify and map historical impacts to seafloor elevation and to determine elevation-change statistics for 12 habitat types found surrounding Maui. Annual elevation-change rates were calculated for each elevation-change data point. Seafloor elevation-change surrounding Maui was projected 25, 50, 75 and 100 years from 1999 using these historical annual rates of elevation change. Water depth was projected 25, 50, 75 and 100 years from 1999 using historical rates of annual elevation change plus 1999 local sea level rise (SLR) data from the National Oceanic and Atmospheric Administration (NOAA).

Processed continuous resistivity profile data collected by the U.S. Geological Survey in Great South Bay on Long Island, New York, on May 21, 2008

An investigation of submarine aquifers adjacent to the Fire Island National Seashore and Long Island, New York, was conducted to assess the importance of submarine groundwater discharge (SGD) as a potential nonpoint source of nitrogen delivery to Great South Bay. More than 200 kilometers (km) of continuous resistivity profiling (CRP) data were collected to image the fresh-saline groundwater interface in sediments beneath the bay. In addition, groundwater sampling was performed at sites (1) along the northern shore of Great South Bay, particularly in Patchogue Bay, that were representative of the developed Long Island shoreline, and (2) at sites on and adjacent to Fire Island, a 50-km-long barrier island on the southern side of Great South Bay. Other field activities included sediment coring, stationary electrical resistivity profiling, and surveys of in-situ pore water conductivity. The onshore and offshore shallow hydrostratigraphy of the Great South Bay shorelines, particularly the presence and nature of submarine confining units, appears to exert primary control on the dimensions and chemistry of the submarine groundwater flow and discharge zones. Sediment coring has shown that the confining units commonly consist of drowned and buried peat layers likely deposited in salt marshes. Based on CRP data, low-salinity groundwater extends from 10 to 100 meters (m) offshore along much of the northern and southern shores of Great South Bay, especially off the mouths of tidal creeks, and beneath shallow flats to the north of Fire Island adjacent to modern salt marshes. Human modifications of much of the shoreline and nearshore areas along the northern shore of the bay, including filling of salt marshes, construction of bulkheads and piers, and dredging of navigation channels, has substantially altered the natural hydrogeology of the bay's shorelines by truncating confining units and increasing recharge near the shore in filled areas. Better understanding of the nature of SGD along developed and undeveloped shorelines of embayments such as this could lead to improved models and mitigation strategies for nutrient overenrichment of estuaries.

Heuristic MODFLOW models used to evaluate the effects of pumping groundwater from confined  aquifers overlain by till confining units

This groundwater-flow model archive contains heuristic model simulations 
evaluating the sustainability of groundwater withdrawals from public-water-supply 
wells on buried glacial aquifers.  A total of 40 steady-state simulations and three 
transient simulations were run.  The steady-state simulations were developed to 
assess the extent and connections between buried sand aquifers by varying 
three hydraulic or dimensional properties of the buried aquifer or overlying tills 
over a range of values observed in field sites near the cities of Akeley, Cromwell, 
Litchfield, and Olivia, Minnesota.

COW_Q34.TIF - U.S. Pacific West Coast EEZ GLORIA sidescan-sonar data mosaic (34 of 36) (TM, 50 m, NAD27)

In March 1983, President Ronald Reagan signed a proclamation establishing an Exclusive Economic Zone (EEZ) of the United States extending its territory 200 nautical miles from the coasts of the United States, Puerto Rico, the Northern Mariana Islands, and the U.S. territories and possessions. In 1984, the U.S. Geological Survey (USGS), Office of Marine Geology began a program to map these areas of the EEZ. The U.S. Pacific Coast was the first EEZ region to be mapped and launched GLORIA (Geological LOng-Range Inclined Asdic) mapping program. The area covered by this survey extended from the Mexican to the Canadian borders and from the continental shelf edge, at about the 400-meter bathymetric contour, to 200 nautical miles from the coast. Survey of the U.S. Pacific West Coast EEZ was completed in four consecutive cruises conducted from late April through mid-August 1984. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 36 digital mosaics of an approximate 2 degree by 2 degree (or smaller) area with a 50-meter pixel resolution were completed for the region.

OahuW_LT- Digital Shoreline Analysis System (DSAS) version 4.2 transects with long-term weighted linear regression rate calculations for the Oahu west region from Yokohama to Tracks Beach, Hawaii

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

Umpqua River Oregon Active Channel 1967

The Umpqua River drains 12,103 square kilometers (4,673 square miles) in southwest Oregon before flowing 
into the Pacific Ocean at Winchester Bay near the city of Reedsport. In cooperation with the Portland District 
of the U.S. Army Corps of Engineers (USACE), the USGS evaluated sediment transport and gravel storage 
along the downstream alluvial reaches of the North and South Umpqua Rivers and the entire mainstem 
Umpqua River. This includes the lower 46.8 kilometers (29.1 miles) of the North Umpqua River and the 
lower 122.6 kilometers (76.2 miles) of the South Umpqua River. 
		
The Umpqua River gravel transport study involved multiple analyses, including tracking patterns of historical 
channel change and estimation of a sediment budget. To support these analyses, digital channel maps were 
produced to depict channel and floodplain conditions along the Umpqua River system from different time periods.
		
GIS layers defining the active channel of the Umpqua River system were developed for three time periods: 
1939, 1967, and 2005. For the South Umpqua River and the 19 kilometers (12 miles) of the mainstem 
Umpqua River downstream from the confluence of the North and South Umpqua Rivers, GIS layers were 
also developed for the time periods 1994, 2000, and 2009.
		
For this project, the active channel was defined as area typically inundated during annual high flows, and 
includes the low-flow channel as well as side channels, islands, and channel-flanking gravel bars. The 
active channel datasets were developed by digitizing from aerial photographs. Aerial photographs from 
1939 and 1967 were scanned, rectified, and mosaiced for this project. Digital orthophotographs from 
1994, 2000, 2005, and 2009 are publicly available (See metadata for each photograph set for more 
information on the rectification process and resolution of each dataset). Although our study area 
encompasses the Umpqua River and lower reaches of the North and South Umpqua Rivers, the 
extent of each dataset depended upon the underlying aerial photographs; for example, the 1967 
photographs extend only as far downstream as floodplain kilometer 7, whereas the 1939 and 2005 
datasets extend to the mouth of the Umpqua River at the Pacific Ocean.
