Items of Interest:

National Maritime Day will be observed-- Next Wednesday, 22 May 2013, has been declared National Maritime Day, a day created to recognize the maritime industry. The holiday was created by the United States Congress on 20 May 1933. The date of 22 May was selected because on 22 May 1819, that the American steamship Savannah set sail from Savannah, GA on the first ever transoceanic voyage under steam power.
CHECK --- The annual European Maritime Day Conference will be held in Valletta, Malta from 21 to 22 May. The theme of this year’s conference is “Sustainable Coastal and Maritime Tourism in the wider context of blue growth.” [Editor's Note: This conference will be held in conjunction with European Maritime Day 2013, which is celebrated annually 20 May with the aim to raise awareness of the importance of the sea among the European citizens. The European Maritime Day was established jointly by the European Council, the European Parliament and European Commission in 2008 as part of the European Union's (EU) maritime policy. EJH]
North American Safe Boating Week -- This week of 18-24 May has been declared 2013 National Safe Boating Week, to help kick off the 2013 North American Safe Boating Campaign. Check the Safe Boating Week site maintained by the Safe Boating Council.

Ocean in the News:

Eye on the tropics --- On last Wednesday, the first day of the official 2013 hurricane season in the eastern North Pacific basin, Tropical Storm Alvin formed from a tropical depression approximately 650 miles to the south-southwest of Acapulco, Mexico. Alvin, the first named tropical cyclone of the season, was relatively short lived, becoming a remnant low within two days of formation as the minimal tropical storm traveled to the west-northwest over the waters of the eastern North Pacific away from the Mexican coast. For additional information on Tropical Storm Alvin along with satellite imagery, see the NASA Hurricane Page. NOTE: The earliest hurricane of the season in the eastern North Pacific basin was Hurricane Alma, a category 1 hurricane on the Saffir-Simpson Scale that formed on 12 May 1990 and reached hurricane status on the 15th.
In the North Indian Ocean basin, Tropical Storm Mahasen traveled to the northwest across the southern Bay of Bengal over last weekend before gradually turning to a northward and then northeastward direction across the central and northern sections of the Bay during the week. Tropical Storm Mahasen, the first tropical cyclone of 2013 in the North Indian Ocean basin, eventually made landfall along the southern Bangladesh coast last Thursday. Torrential rains from rainshowers and thunderstorms associated with Mahasen fell across Bangladesh, India and Myanmar (formerly called Burma). At least 13 fatalities attributed to Mahasen were reported in Bangladesh. As many as 50 people were feared to be drowned after their boats capsized in the Bay of Bengal off the coast of western Burma due to the strong winds associated with Mahasen. The NASA Hurricane Page has additional information and satellite images on Tropical Storm Mahasen.
Citizen science effort helps classify tropical cyclone imagery --A collaborative project reached a milestone last week with 200,000 classifications of tropical cyclone images. This project represents a collaboration between NOAA's National Climatic Data Center, the Cooperative Institute for Climate and Satellites-North Carolina, the University of North Carolina-Asheville, and the Citizen Science Alliance (CycloneCenter.org) The project's aim is to address uncertainties in the global tropical cyclone record by enlisting volunteers from the public to help classify tropical cyclone imagery.

Final service assessment report on Hurricane Sandy released -- During the last week, NOAA released a report entitled Hurricane/Post Tropical Cyclone Sandy Service Assessment reviewing the performance of NOAA's National Weather Service during Hurricane/post-Tropical Cyclone Sandy that made landfall along the New Jersey coast last October. The report indicates that NWS provided accurate forecasts for Sandy, which gave people along the Atlantic Seaboard early awareness of this weather system. However, certain problems were found with NOAA's ability to communicate the impending impacts associated with the storm surge that represented one of the most significant hazards associated with Sandy. The report also includes 23 recommendations designed to improve NWS products and services that would help meet future needs of the public and other governmental agencies.[NOAA News]
Public invited to comment on new Steller sea lion protection measures ....-- During the last week NOAA Fisheries released for public review and comment a copy of new fishery management measures intended to protect Steller sea lions as part of a draft environmental impact statement for Alaska's Bering Sea and Aleutian Islands Management Area. The western distinct population segment of Steller sea lions are listed as endangered under the Endangered Species Act. In addition to protecting the Steller sea lions, the proposed fishery management measures would reduce economic impacts on the Atka mackerel, Pacific cod, and pollock fisheries in the Aleutian Islands.

"Fish thermometer" shows how climate change impacts global fisheries -- Researchers at the University of British Columbia have devised a "fish thermometer" that uses the temperature preferences of fish and other marine species to assess the effects of changing climate on the world's oceans in the last four decades. The researchers found that changes in climate, as indicated primarily by rising global temperatures, have driven marine species to cooler and deeper waters. They also discovered that global fisheries catches were increasingly dominated by warm-water species due to the migration of fish toward polar latitudes in response to higher ocean temperatures.

Satellite data helps determine role of glaciers in sea-level rise -- An international team of researchers using data obtained from NASA's Ice, Cloud, and Land Elevation Satellite (ICESat) and from its Gravity Recovery and Climate Experiment (GRACE) missions have determined the contribution of glaciers worldwide to the changes in sea level. They found that those glaciers exclusive of the Greenland and Antarctic ice sheets lost an average of 571 trillion pounds of mass every year during the six-year study, making the oceans rise 0.03 inches per year. These glaciers contain only one percent of all land ice, but contributed to about 30 percent of the total observed global sea level rise between 2003 and 2009. [NASA Headquarters]

Historical Events:

20 May 1497...John Cabot set sail from Bristol, England, on his ship The Mathew looking for a route to the west (other documents give a 2 May date). (Wikipedia)

20 May 1964...The first U.S. atomic-powered lighthouse was put into operation in the Chesapeake Bay, Baltimore Harbor, MD. Designed to supply a continuous flow of electricity for ten years without refueling, the 60-watt nuclear generator generated heat from strontium-90 in the form of strontium titinate, a safe radioisotope. The heat was converted to electricity by 120 pairs of lead telluride thermocouples. Complete with shielding, the unit was only 34.5 inches high and 22 inches in diameter. It was designed and produced by the nuclear division of Martin-Marietta Corp. (Today in Science History)

24 May 1992...Winds up to 40 knots and seas to 18 feet in the northern Gulf of Alaska, approximately 30 miles southwest of Alaska's Cape Cleare, sent three waves crashing over the Cajun Mama. The 80-ft fishing boat sank, but the crew of five was rescued. (Accord's Weather Guide Calendar)
25 May 1985...The Meghna River delta in Bangladesh was hit with a tropical cyclone with winds of over 100 mph that created a 15-to 20-foot high storm surge that flooded a 400-square-mile area, mainly islands located in the mouth of the river.
