Items of Interest:
- Check Zenithal Sun -- Residents of Hawaii's Big Island will
experience a noontime sun that would be directly overhead during this week
(22-23 Jul). This occurrence of a zenithal sun is one of the two times during
the year when the noontime sun is directly overhead to residents of Hilo and
elsewhere on the Big Island. approximately one more week.. The other time when
the Big Island experienced a zenithal sun was in mid May. [US Naval Observatory, Data Services]
- A new moon and solar eclipse -- A new moon will occur this evening
(officially 0235Z on 22 July 2009 or 10:35 PM EDT and 9:35 PM CDT, etc. on
Monday).
Since lunar perigee (closest approach of the Moon to the Earth) of the year
occurs only six hours before new moon, extremely high astronomical tides are
predicted for large water bodies.
This new moon will also be responsible for a total solar eclipse for those
located in parts of China and across the western Pacific Ocean, as the moon
passes in front of the solar disk. The
NASA Eclipse
Web Site has more particulars and maps of this solar eclipse.
- Marking the 40th anniversary of the "Giant Leap" -- This
coming week marks the 40th Anniversary when Neil Armstrong and "Buzz"
Aldrin were the first humans to set foot on the lunar surface after the Apollo
11 landing on the moon. NASA is celebrating this anniversary with a variety of
features on their home page. [NASA] A

A group of 29 noted scientists at universities across the nation and
representing various disciplines were asked by The Science Coalition to proved
their perspectives of how this historic lunar landing affected their
disciplines and on what efforts are needed to meet the challenges of the next
frontier of science. [EurekAlert!]
Ocean in the News:
- Eye on the tropics --- Some tropical cyclone activity was found
across the tropical Pacific during the past week:
- In eastern North Pacific, the fourth tropical storm of the 2009 hurricane
season, Tropical Storm Dolores, formed at midweek well off the Mexican coast
and moved to the northwest. By the end of the week, this system dissipated. For
more information on Dolores including satellite images, consult the
NASA
Hurricane page.
Tropical Storm Carlos, which had formed during the previous week, became the
second hurricane of the 2009 eastern North Pacific hurricane season early last
week. This system, which briefly became a category 2 hurricane (on the
Saffir-Simpson Scale), dissipated after moving westward to near 140 degrees
West longitude, the western boundary of the eastern North Pacific basin.
Satellite images, together with additional information on Carlos can be found
on the
NASA
Hurricane page.
- In western North Pacific basin, the tropical cyclone known as Isang when it
was near the Philippines was renamed Typhoon Molave as it traveled to the west
northwest across the South China Sea. This system became a category 1 typhoon
before making landfall along the coast of southeastern China over this past
weekend. Additional information along with satellite images are featured in the
NASA
Hurricane page.
- Flooding and damage from deadly tropical cyclone assessed -- A
survey team recently reported their findings on the flooding and damage caused
by a category 4 tropical cyclone (on the Saffir-Simpson Scale) that made
landfall in May 2008 on the coast of the southeast Asian nation of Myanmar,
resulting in the deaths of at least 138,000 people. [EurekAlert!]
- New seasonal hurricane forecast model unveiled -- Scientists at
Florida State University's Center for Ocean-Atmospheric Prediction Studies have
developed a new "dynamical" computer model designed to predict the
frequency of hurricane occurrence during a given season with unprecedented
accuracy. Using this model, they forecast a below-average season in the
Atlantic Ocean due in part on emerging El Niño conditions. [EurekAlert!]
- Record warm global ocean waters reported in June 2009 -- Analysis of
preliminary average global land and ocean surface temperature data for the
recently concluded month of June 2009 has led researchers at NOAAs
National Climatic Data Center to conclude that the world's ocean surface
temperature was the highest for June since the start of worldwide records in
1880. They also noted that the global land surface temperature was the sixth
highest in the last 130 years, making the combined global land and ocean
surface temperature for June 2009 was the second highest on record. [NOAA
News]
Increasing sea surface temperatures across the equatorial Pacific Ocean has
lead NOAA scientists at NCDC and the Climate Prediction Center (CPC) to
conclude that El Niño conditions have returned. Therefore, CPC has
declared an El Niño Advisory, indicating that El Niño conditions
are now being observed and are expected to persist. These forecasters
anticipate that El Niño conditions should persist through the upcoming
Northern Hemisphere winter of 2009-10. [NOAA/NCEP

NASA scientists at the Jet Propulsion Laboratory are also monitoring sea
surface altimetry data obtained the Jason-2 satellite, looking for the spread
of warm water across the equatorial Pacific.

- Tsunami research forecast system put to the test -- Tsunami
scientists attending an international meeting in Russia last week were able to
see the web-based NOAA tsunami forecast system in action as real-time tsunami
data from the DART® (Deep-ocean Assessment and Reporting of Tsunamis)
tsunami monitoring system were accessed when a tsunami was generated by a large
earthquake off the southwest coast of New Zealand. [NOAA
News]
- Detecting tsunamis from space -- Scientists from NOAAs Earth
System Research Laboratory and the Cooperative Institute for Research in
Environmental Sciences recently reported tracking a tsunami propagating across
the open ocean using satellite-borne radar units to detect changes in sea
surface texture along the leading edge of the wave. These scientists feel that
this information obtained by orbiting satellites could be used to aid in
improved tsunami detection and warning. [NOAA
News]
- Important extreme weather information available to Florida East Coast
residents -- An easily read waterproof tip-sheet containing emergency
telephone numbers and website information needed during potentially
life-threatening weather emergencies by residents of Floridas Atlantic
coast is now available. This sheet is part of the popular NOAA Extreme Weather
Information Sheet series (NEWIS) prepared by NOAAs National Coastal Data
Development Center. [NOAA
News]
- Coastal wetlands restored in the Lone Star State -- A cooperative
agreement between NOAA, the US Fish and Wildlife Service, the Texas Commission
on Environmental Quality, the Texas Parks and Wildlife Department, the Texas
General Land Office and the Chevron Corporation has resulted in the restoration
of more than 2500 acres of coastal wetland habitats in the Lower Neches Water
Management Area in Port Arthur, TX that were injured by refinery releases. [NOAA
News]
- First underwater detection of harmful algae made -- Scientists at
NOAAs National Centers for Coastal Ocean Science and the Monterey Bay
Aquarium Research Institute (MBARI) recently reported that they have used the
Environmental Sample Processor (ESP), a MBARI-designed robotic instrument to
remotely detect harmful algal species and its toxin below the oceans
surface for the first time. [NOAA
News] [MBARI]
- Commercial harvesting of krill off West Coast is banned -- A rule
developed by NOAA was recently published in the Federal Register that would
prohibit the harvesting in the Exclusive Economic Zone off the California,
Oregon and Washington coasts, effective in August 2009. This measure is meant
to protect a vital food source for many marine species along the nation's
Pacific Coast. [EurekAlert!]
- Arctic sea ice campaign is underway-- A new NASA-sponsored
scientific field campaign called CASIE-09 (Characterization of Arctic Sea Ice
Experiment 2009) is currently being conducted under the auspices of the
International Polar Year (IPY) to study sea ice roughness and break-up in the
Arctic and high northern latitudes. A variety of remote sensing methods will be
utilized, including satellites and uninhabited aerial vehicles. [NASA ESPO] [EurekAlert!]
- Declassification of arctic images should proceed to help in climate
change examination -- A new report, entitled "Scientific Value of
Arctic Sea Ice Imagery Derived Products," from the National Research
Council requests that arctic images obtained from classified data sources
should be declassified and made available to scientists and others for studies
that involve detailed melting and freezing processes in the Arctic basin, which
would be extremely useful studying the effects of climate change on sea ice and
habitat. [National
Academies]
- A "motion picture" of a past warming event may give clue to
future -- Researchers at the University of Wisconsin-Madison's Center from
Climatic Research have run a computer simulation of the atmospheric and oceanic
conditions over the last 21,000 years, focusing Bølling-Allerød
warming event (approximately 14,500 years ago), which may provide some
understanding to what abrupt climate shifts that could occur in the future with
additional warming of the planet. [EurekAlert!]
- Gradual changes in North Atlantic currents are indicated -- A
geosciences professor at Oregon State University claims that one of the longest
experiment of its type ever run on a general circulation model to simulate the
Earth's climate for the last 21,000 years indicates that major changes occur in
the important ocean current systems since the height of the last Ice Age, but
these changes in the North Atlantic Ocean may take place more slowly and
gradually than had been suggested. [EurekAlert!]
- An earlier formation of Arctic sea ice suspected -- An international
team of researchers from the United Kingdom and Norway who have been analyzing
oceanic sediment cores collected by the Integrated Ocean Drilling Program
Expedition from the floor of the central Arctic Ocean basin have
concluded that ice may have initially formed in the Arctic between 47.5 and 46
million years ago, earlier than previously thought. [EurekAlert!]
- Looking back at ancient life -- Researchers from the California
Institute of Technology and NASA's Jet Propulsion Laboratory conclude that some
of the most ancient stromatolites were built with the assistance of mat-like
microorganism communities approximately 3.4 billion years ago. [EurekAlert!]
- Demise of salt marshes may be linked to climate change -- Research
conducted at Brown University indicates that increased atmospheric temperatures
could place major stresses on several types of plants that inhabit pannes, or
waterlogged, low-oxygen zones of salt marshes, in New England. [EurekAlert!]
- An All-Hazards Monitor --This Web portal provides the user
information from NOAA on current environmental events that may pose as hazards
such as tropical weather, marine weather, tsunamis, rip currents, Harmful Algal
Blooms (HABs) and coral bleaching. [NOAAWatch]

Historical Events:
- 20 July 1964...Four Navy divers entered Project SEALAB I capsule moored 192
feet on the ocean floor off Bermuda for a 11-day experiment. On the
22nd they submerged and then surfaced on 31 July 1964. (Naval
Historical Center)
- 20 July 1985...Treasure hunters found the Spanish galleon Nuestra Senora
de Atocha, which sank approximately 40 miles off the coast of Key West, FL,
in 1622 during a hurricane. The ship contained over $400 million in coins and
silver ingots. (InfoPlease.com)
- 22 July 1986...Hurricane Estelle passed 120 miles south of the Hawaiian
Islands creating a ten to twenty-foot surf. The large swells resulted from a
combination of high tides, a full moon, and 50-mph winds. The hurricane also
deluged Oahu Island with as much as 6.86 inches of rain on the 24th and 25th of
the month. (Storm Data)
- 22-23 July 1996...A strong storm system centered south of Tahiti in the
South Pacific was responsible for eight-foot surf along the south shores of
Hawaii's Oahu Island. Water safety personnel rescued 95 people from the high
surf. (Accord's Weather Guide Calendar)
- 23 July 1715...Boston Light, the first lighthouse in America was authorized
by the Boston Light Bill for construction at Little Brewster Island, MA. This
light, located on Little Brewster Island to mark the entrance to Boston harbor,
has guided ships since its lantern was first lighted just before sunset, on 14
Sep 1716. In the 1600s, treacherous rocks caused countless loss of lives. False
signal fires lit in the wrong places by "wreckers" lured ships
aground to plunder. Boston Light was blown up by the British in 1776, but
rebuilt in 1783 by Governor John Hancock. The lighthouse was also the last
remaining staffed station in the U.S. (Today in Science History)
- 23 July 1788...A weather diary kept by George Washington recorded that the
center of a hurricane passed directly over his Mount Vernon home. The hurricane
crossed eastern North Carolina and Virginia before moving into the Central
Appalachians. Norfolk, VA reported houses destroyed, trees uprooted, and crops
leveled to the ground. (David Ludlum)
- 23 July 1958...USS Nautilus (SSN-571) departed Pearl Harbor, Hawaii
for the first submerged transit of the North Pole. (Naval Historical Center)
- 23 July 1982...The International Whaling Commission decided to end
commercial whaling by 1985-86. (Wikipedia)
- 24 July 1609...A fleet of ships carrying colonists to the New World met
with a hurricane near Bermuda, resulting in much loss of property but little
loss of life. (Northern Indiana NWSFO)
- 24-25 July 1979...Claudette, a weak tropical storm, deluged southeastern
Texas with torrential rains. The Houston suburb of Alvin received 43.00 inches,
a 24-hour precipitation record for not only the Lone Star State, but for the
U.S. Freeport reported a total of 30 inches. Total damage from flooding was
over $400 million. On the 27th, a van loaded with people on their
way to a church camp stopped on Texas Highway 7 due to a flooded bridge just
west of Centerville. A truck rammed the van, pushing it into the flooded creek,
resulting in five people drowning. (Intellicast) (David Ludlum) (NCDC)
(Accord's Weather Guide Calendar)
- 24-26 July 1996...Although thousands of miles from southern California, an
intense South Pacific storm south of Tahiti produced seven to ten foot surf
with some sets up to 12 feet along the southern California coast. Lifeguards
participated in more than 500 rescues along the beaches. (Accord's Weather
Guide Calendar)
- 25 July 1956...The Italian ship Andrea Doria sank in dense fog near
Nantucket Lightship, MA. Ten hours earlier, the ship was rammed by the
Swedish-American liner, Stockholm, forty-five miles off the coast of
Massachusetts. Fifty-two persons drowned, or were killed by the impact. (David
Ludlum) (The Weather Channel)
- 25 July 1994...Hurricane Gilma, like Emilia a week earlier, reached
Category 5 strength in the Central Pacific. (Intellicast)
