US Navy Sailors Dive Into Aquarium Exhibits

Sailors assigned to the U.S. Naval Academy and Explosive Ordnance Disposal (EOD) Mobile Unit 12 dove with more than 1,000 fish in the Western Atlantic tank exhibit at the National Aquarium in Baltimore to show off Navy diving assets as part of Maryland Fleet Week and Air Show Baltimore (MDFWASB), October 4.This display of fins and bubbles attracted more than 200 visiting students. While leaning on the walls of the 330,000-gallon aquarium, children watched and interacted with the divers using hand signs and also posed for pictures with the Sailors.In addition to interacting with hundreds of visitors

Underwater target tracking technology from Houston-based Sonardyne Inc., has been chosen by the U.S. Naval Surface Warfare Center (NSWC), Carderock Division for testing subsea systems and underwater vehicles in development for the Navy and wider maritime industry.Located in Maryland, Carderock Division is the U.S. Navy's research, engineering, modelling and test center for surface and undersea technologies. It is the largest, most comprehensive establishment of its kind in the world. Thanks to its proximity to the Gulf Stream, Carderock’s South Florida Ocean Measurement Facility (SFOMF)

in recent years: in 2015 the U.S. Department of Energy published a nationwide wind study, which contemplates 22 gigawatts (GW) of wind energy deployment by 2030 and 86 GW by 2050. The first offshore wind farm is now in operation.  At the same time, the states of Massachusetts, New York, Maryland and New Jersey have established specific targets for offshore wind development: according to targets that have already been released, up to 8 GW of offshore wind should be in operation by 2030. 

The William B Morgan Large Cavitation Channel (LCC) is a large variable-pressure closed-loop water tunnel that has been operated by the U.S. Navy in Memphis since 1991. This facility is well designed for a wide variety of hydrodynamic and hydroacoustic tests. Its overall size and capabilities allow test-model Reynolds numbers to approach, or even achieve, those of full-scale air- or water-borne transportation systems. (Photo: U.S. Navy)

The center also has access to a reservoir in Maryland where scaled models of both ships and submarines are tested.But some of Carderock’s most impressive capabilities reside far away, at facilities from the Alaska to the Bahamas, and from Tennessee to Idaho.Carderock’s Combat Craft division in Little Creek, Va., manages a number of small

US Rivers Getting Saltier, Drinking Water at Risk -Study

from rocks and soil in streams. The study found that a combination of salts can do more damage than one salt alone.   "Until now we didn't fully appreciate the role that different salts play in altering the pH of streams and rivers of our country," said Sujay Kaushal, a University of Maryland geologist and the lead scientist of the study, published in the early edition of the Proceedings of the National Academy of Sciences. The study also looked at waterways in southern Canada.   Increased salt levels of waterways was a factor in the lead poisoning crisis in Detroit, in which

Working with commercial lobstermen, the project will remove over 100 metric tons of derelict gear debris.   The County of Prince George ($150,000) will install two floating litter traps in the Anacostia River in Maryland to reduce the debris loads flowing downstream towards the Potomac River and eventually the Chesapeake Bay. The County will also monitor the effectiveness of this removal approach, and increase public awareness of marine debris through local outreach and education programs.   Island

Today we’re tracking over 90 satellites, not only from NASA, but also from other space agencies with this technique.”   The new Norwegian geodetic station will be the northernmost

Proposed Sanctuaries Aim to Protect Historic Shipwrecks

The U.S. National Oceanic and Atmospheric Administration (NOAA) has released draft plans for proposed national marine sanctuaries in Wisconsin and Maryland that would aim to protect nationally significant shipwrecks, including those from the 1800s, World War I and other maritime battlegrounds. The sanctuaries were originally proposed to NOAA in 2014, and if created would be the first since 2000. In Wisconsin, NOAA is proposing to designate a 1,075-square-mile area of Lake Michigan adjacent to Manitowoc, Sheboygan and Ozaukee counties that holds 37 known shipwrecks including Wisconsin's two
