DataStreme Ocean will return for Fall 2009 with new Investigations files
starting during Preview Week, Monday, 31 August 2009. All the current online
website products will continue to be available throughout the summer break
period.
Ocean in the News:
- Eye on the tropics -- Although sea surface temperatures have been
increasing across the ocean basins of the Northern Hemisphere, tropical cyclone
activity has been relatively non-existent this past week. (Tropical cyclones
are low-pressure systems over tropical waters.) On Sunday, a tropical storm
with maximum sustained surface winds of 40 mph had developed over the waters of
the Bay of Bengal off the eastern coast of India. This system is the second
tropical cyclone of the 2009 season in the Northern Indian Ocean.
- Hurricane Preparedness Week -- With the beginning of the official
2009 hurricane season for the North Atlantic Basin beginning on 1 June, next
week (24-30 May) has been declared National Hurricane Awareness Week. The
National Hurricane Center maintains a
hurricane
preparedness website that provides information and educational material for
the various hurricane hazards to include storm surge, high winds, tornadoes and
flooding. (A Spanish
version of this website is also available.)
- Hurricane outlooks issued -- Scientists with NOAA's Climate
Prediction Center have released their outlooks for the upcoming hurricane
seasons in the Atlantic, the eastern Pacific and central Pacific Basins last
week:
- For the North Atlantic basin, the outlook indicates
equal chances (50 percent) of near normal hurricane activity, while the
probabilities of above and below normal seasons were set at 25 percent chance
each. Specifically, the outlook calls for a 70 percent chance of nine to 14
named tropical cyclones (hurricanes and tropical storms), including four to
seven hurricanes, with one to three major hurricanes (Category 3 hurricanes or
greater on the Saffir-Simpson Hurricane Intensity Scale). The forecasts point
to the uncertainty in their hurricane forecasts as being due to uncertainty in
the global weather patterns. Competing factors also include a recent trend
toward more active Atlantic hurricane seasons during the last decade, enhanced
West African rainfall and reduced wind shear warmer Atlantic waters, along with
the possibility of the development of an El Niño event. [NOAA
News] For comparison, Phil Klotzbach and Bill Gray at Colorado State
University released an updated forecast of the 2009 Atlantic hurricane season
in early April calling for a season with slightly above average activity with
12 named tropical cyclones (tropical storms and hurricanes), of which six could
reach hurricane status.
- For the Eastern North Pacific basin (east of 140 degrees West
longitude), the outlook from NOAA's Climate Prediction Center suggests a normal
to below-normal hurricane season. This outlook would call for a 70 percent
chance of 13 to 18 named tropical cyclones, with six to ten hurricanes and two
to five major hurricanes; which compares with the long-term average of 16 named
cyclones, nine hurricanes and as many as five major hurricanes. The forecasters
indicate that the slightly lower than average season may be influenced by the
atmospheric conditions that have decreased hurricane activity over the basin
during the last decade and the possible development of an El Niño event.

News]
- For the Central North Pacific basin (between 180 degrees and
140 degrees West longitude), Forecasters at NOAA's Central Pacific Hurricane
Center in collaboration with their colleagues at the Climate Prediction Center
expect that the upcoming season has an 80 percent chance of being a near- to
below-normal season. On average, four to five tropical cyclones (including
tropical depressions, tropical storms and hurricanes) travel across the basin.
The lower than average anticipated numbers could be related to the uncertainty
in the current predictions of El Niño conditions. [NOAA
News]
- Review of April 2009 global temperatures -- After their analysis of
preliminary data, scientists at NOAAs National Climatic Data Center
recently reported that the combined average global land and ocean surface
temperatures for April 2009 were the fifth highest since sufficiently dense
worldwide records began in 1880. Southern oceans, along with sections of Europe
and northern Asia were unseasonably warm.
In addition, scientists at the National Snow and Ice Data Center reported that
the extent of the Arctic sea ice was the tenth smallest since satellite
surveillance began in 1979, while sea ice cover on the Southern Oceans was
approximately 13 percent greater than the 1979-2000 average. [NOAA
News]
- Several fish stocks have been rebuilt -- NOAAs Fisheries
Service recently provided the US Congress with the "2008 Status of U.S.
Fisheries," reporting that four fish stocks in the Atlantic have been
rebuilt sufficiently to allow for continued sustainable fishing. These stocks
were Atlantic bluefish, Gulf of Mexico king mackerel and two stocks of
monkfish. Several other stocks were placed on the list of those that are being
fished at unsustainable levels. [NOAA
News]
- Public comment sought on protection of threatened sturgeon --
NOAAs Fisheries Service is seeking public comment on a proposed rule
prohibiting acts that would kill or harm a threatened group of North American
green sturgeon that spawn in California's Sacramento River. [NOAA
News]
- Changes in fisheries catches affected by warmer oceans -- NOAA
scientists have made key contributions to a new United Nations Environment
Programme report entitled "The UNEP Large Marine Ecosystem Report: a
Perspective on Changing Conditions in LMEs of the Worlds Regional
Seas" in which 61 of the worlds 64 large marine ecosystems (LMEs)
located in the coastal waters adjacent to continents have experienced a
significant increase in sea surface temperatures during the last 25 years,
contributing to changes in the fisheries catches. [NOAA
News]
- Maritime heritage of African-Americans is explored -- Over this past
weekend, NOAA archaeologists helped train members of the National Association
of Black Scuba Divers in underwater archaeology at the Florida Keys National
Marine Sanctuary. This training has been part of a new education initiative
designed to explore the maritime heritage of African-Americans and engage the
community in marine resource conservation. [NOAA
News]
- Sounds of endangered whales comes from an unlikely region of the North
Atlantic -- Using hydrophones deployed in North Atlantic waters off the
southern tip of Greenland, a team of scientists from NOAAs Pacific Marine
Environmental Laboratory, NOAAs National Marine Mammal Laboratory and
Oregon State University were able to hear the distinctive calls of the
endangered North Atlantic right whales. This discovery is significant, as the
sounds came from a region where the resident whale population was thought to
have been hunted to extinction during the early 20th century. This region is
along potential shipping lanes of the Northwest Passage that could see
increased activity because of more open water in the future. [NOAA
News]
- An in depth report made on the Northwestern Hawaiian Islands' ecosystems
-- NOAAs National Center for Coastal Ocean Science has prepared a
report entitled, "A Marine Biogeographic Assessment of the Northwestern
Hawaiian Islands" that examines in detail the marine life and habitats of
the Northwestern Hawaiian Islands, especially in the region protected by the
Papahnaumokukea Marine National Monument. [NOAA
News]
- Heat-tolerant coral reefs found that may resist warmer ocean waters --
Stanford University scientists have found evidence that some coral reefs
are adapting to warmer ocean waters and may survive anticipated global warming.

University]
- Students selected for Hollings Scholarships -- The Director of
NOAAs Office of Education recently announced the names of the 122 college
undergraduates who will receive scholarships as part of the Ernest F. Hollings
Undergraduate Scholarship Program. These scholarships, named for former Senator
Ernest F. Hollings of South Carolina, are provided to encourage undergraduates
to pursue studies in those sciences found in NOAA, including the atmospheric
and oceanic sciences. [NOAA

Historical Events:
- 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. More than 11,000 people and 500,000 head of cattle died and
hundreds of thousands were left homeless because of this cyclone.
- 26 May 1967...A slow moving nor'easter battered New England with high
winds, heavy rain, and record late season snow on this day and into the 26th.
Winds 70 to 90 mph in gusts occurred along the coast. Over 7 inches of rain
fell at Nantucket, MA with 6.57 inches falling in 24 hours to set a new 24-hour
rainfall record. Severe damage occurred along the coast from very high tides.
The 24.9 inches of snow that fell at Mount Washington, NH set a new May
snowfall record. Other locations in New Hampshire received 10 inches of snow
near Keene and 6 inches at Dublin. (Intellicast)
- 28 May 1963...A cyclone killed about 22,000 people along the coast of East
Pakistan.
- 28 May 1987...A robot probe found the wreckage of the USS Monitor
off Cape Hatteras, NC. (Wikipedia)
- 29 May 1827...The first nautical school was opened in Nantucket, MA, under
the name Admiral Sir Isaac Coffin's Lancasterian School.
- 29 May 1914...Shallow river fog along the St. Lawrence River approximately
185 miles from Quebec City, Quebec contributed to the collision of the CP Liner
Empress of Ireland and a Norwegian coal ship, The Storstad.
Although the two ships had spotted each other several minutes before the
collision, altered courses and confused signals contributed to the crash. In
one of the worst ship disasters in history, the liner sank in 25 minutes
drowning 1024 passengers of the 1477 people on board. Only seven lifeboats
escaped the rapidly sinking vessel. (The Weather Doctor) (The History Channel)
- 29 May 1950...A Royal Canadian Mounted Police schooner, RCMPV St.
Roch, became the first ship to circumnavigate North America, when it
arrived in Halifax, Nova Scotia. (Wikipedia)
- 30 May 1767...The first stone of the tower for the Charleston Lighthouse on
Morris Island, SC was laid on this date. (USCG Historian's Office)
- 30-31 May 1997...As many as 140 people had to be rescued from rip currents
off Dayton Beach Shores, FL. One man died in a rip current while trying to save
his wife. (Accord's Weather Guide Calendar)
- 31 May 1911...The hull of the ill-fated Titanic was launched in
Belfast, Northern Ireland. At the ceremony, a White Star Line employee claimed,
"Not even God himself could sink this ship." (Information Please)
- 31 May 1997...The Confederation Bridge, also dubbed the "Fixed
Link," was officially opened, linking Canada's Prince Edward Island with
mainland New Brunswick. This 8-mile long bridge that crosses the Northumberland
Strait is the longest bridge in the world that spans waters that freeze.
