Seismic, geologic, and bathymetric data near the Atlantis Massif give new clues to the formation of oceanic crust
The theory of plate tectonics explains the evolution and morphological change of the Earth’s surface features throughout time. Less clear, however, are the underlying processes that occur at plate boundaries to create new crust and recycle old. Researchers on the JOIDES Resolution, one of only a few research-focused ocean-drilling vessels in service, are attempting to shed light on these processes by studying seismic and geologic data collected at the Atlantis Massif seamount.
Mapping Oregon’s wave energy future
The Oregon State Waters Mapping Program was developed to map critical areas of the Oregon Territorial Sea in order to establish a baseline for managing state marine assets, including the possibility of harnessing wave energy as an alternative energy source. As part of this initiative, data gathered from public sources (such as NOAA and the USGS) and privately contracted survey companies are helping update regional seafloor maps to establish optimal areas off the Oregon coast for the potential deployment of wave energy harnessing devices. That data is available now via OneOcean.
Acoustic data surveying fish populations in ecologically significant areas near the U.S. Virgin Islands
NOAA scientists aboard the NOAA ship Nancy Foster have completed a bathymetric survey of unexplored areas between 3 and 30 kilometers off the coast of St. Thomas and St. John in support of coral reef conservation efforts and seafloor exploration. In addition to multibeam data, acoustic data collected from sound waves reflected off fish swim bladders gave researchers insight to the number and size of fish in the area. Check out the ClipCards of this unique data in Map View.
Multibeam data exposes hurricane hazards in Block Island Sound
As part of a multi-year effort to map the coastlines near New York, Connecticut, and Rhode Island, the Office of Coastal Survey has been surveying the waters in Block Island Sound with hopes that updated nautical charts will ensure navigational channels remain open for shipping, fishing, and other marine-based industries. As Hurricane Sandy showed, hazards to New York and New Jersey harbors can suffer the same problems that port authorities in the southeast United States have dealt with for years: excessive sedimentation and runoff, reduced access to local utilities from debris, and pollution to surrounding waters due to sewage flushed into waterways, to name a few.
A first look at Delgada Canyon in high resolution
The mouth of Delgada Canyon was mapped as part of a Fugro Pelagos, Inc. survey, contracted by NOAA and the California Coastal Conservancy, to update nautical charts and fisheries habitat maps. The data was later archived and made available to the public by the National Geophysical Data Center, and is hosted by OneOcean for easy public access. View the ClipCards in Map View for more information about the data available.
NOAA’s Rainier is collecting vital data for fisheries and tsunami models along the Alaskan coast
The NOAA ship Rainier is currently surveying Alaskan coastal waters near Prince of Wales Island as part of a multiyear effort to update nautical charts, support marine ecosystem studies, and improve inundation models for tsunami-vulnerable areas. View the ClipCards for most recently available surveys, and stay tuned to OneOcean as new data is added.
Proactive data management critical to aiding post-hurricane responses on the Gulf Coast
Hurricanes can result in billions of dollars of impact, not just in damages but also in income lost to economic impedance to maritime industries and coastal communities. To manage and combat these issues, NOAA’s Office of Coastal Survey hopes that preemptively mobilizing assets in order to rapidly deploy marine survey teams will minimize shipping delays and maritime accidents caused by hurricane-displaced debris.
