Hurricane Sandy's Coastal Legacy Lidar Revealed

Lidar confirms Sandy’s dramatic coastal change Impacts and future coastal vulnerability to US Geological Survey. The extent of Hurricane Sandy's wrath -- and the future coastal vulnerability of the region -- is clear in a new U.S. Geological Survey analysis of recently collected lidar coastal data. The research documented particularly dramatic impacts within the Fire Island National Seashore on Long Island, NY . Lidar, or light detection and ranging, uses lasers to measure elevations in a specific distance/area. Researchers used the lidar data, collected during an airborne survey, to construct a high-resolution three-dimensional map of before- and after-storm conditions.

Sea Level Rise Accelerating in U.S. Atlantic Coast “Hotspot”

Rates of sea level rise are increasing three-to-four times faster along portions of the U.S. Atlantic Coast than globally, according to a new U.S. Geological Survey report published in Nature Climate Change. Since about 1990, sea-level rise in the 600-mile stretch of coastal zone from Cape Hatteras, N.C. to north of Boston, Mass. -- coined a “hotspot” by scientists -- has increased 2 - 3.7 millimeters per year; the global increase over the same period was 0.6 – 1.0 millimeter per year. Based on data and analyses included in the report, if global temperatures continue to rise, rates of sea level rise in this area are expected to continue increasing. The report shows that the sea-level rise hotspot is consistent with the slowing of Atlantic Ocean circulation.

USGS’s R/V Kaho & R/V Muskie Dedicated

Two 17-knot high-speed research vessels for the U.S. Geological Survey are scheduled to be dedicated at Great Lakes Shipyard, Cleveland, Ohio, on Wednesday, August 31, 2011. R/V KAHO and R/V MUSKIE will replace two of the USGS’s oldest research vessels by the same names that are currently operating on Lake Ontario and Lake Erie, respectively. The USCG’s five-vessel fleet supports missions that collect and analyze oceanographic and fisheries information. The U.S. Department of Interior’s U.S.

"Today I met with Secretary Chu, Marcia McNutt and other scientists and geologists as well as officials from BP and other industry representatives as we continue to prepare and review protocols for the well integrity test - including the seismic mapping run that was made around the well site this morning. As a result of these discussions, we decided that the process may benefit from additional analysis that will be performed tonight and tomorrow. “Both the Helix Producer and the…

New Improved Estimate of Oil Spill Flow Rate

Based on updated information and scientific assessments, Secretary of Energy Steven Chu, Secretary of the Interior Ken Salazar, and Chair of the National Incident Command’s Flow Rate Technical Group (FRTG) Dr. Marcia McNutt (Director of the U.S. Geological Survey) today announced an improved estimate of how much oil is flowing from the leaking BP well. Secretary Chu, Secretary Salazar, and Dr. McNutt convened a group of federal and independent scientists on Monday to discuss new analyses and data points obtained over the weekend to produce updated flow rate estimates. Working together, U.S. government and independent scientists estimate that the most likely flow rate of oil today is between 35,000 and 60,000 barrels per day.

Updated Flow Rate Analysis from BP’s Well

Under the direction of National Incident Commander Admiral Thad Allen, the Flow Rate Technical Group (FRTG), which is led by United States Geological Survey Director Dr. Marcia McNutt, and a scientific team led by Energy Secretary Steven Chu are analyzing new data and bringing together several scientific methodologies to develop an updated estimate of how much oil is flowing from BP’s leaking oil well in the Gulf of Mexico. The updated estimate, which will bring together the ongoing work of scientists and engineers from the federal government, universities, and research institutions, will be of how much oil has been flowing since the riser was cut on June 3.
