: "For three weeks, a titanium-encased hydrophone recorded ambient noise from the ocean floor at a depth of more than 36,000 feet, or 7 miles, in the Challenger Deep trough in the Mariana Trench near Micronesia. Researchers from NOAA, Oregon State University, and the U.S. Coast Guard were surprised by how much they heard." The hydrophone recorded the sounds of whales, ships' propellers, typhoons, and an earthquake. [more inside]
The world's coral is suddenly and rapidly starting to die
- "This is only the third time
we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row." Can 'manually breeding supercorals capable of living in increasingly inhospitable waters

Since January there have been signs of a possible El Niño brewing in the pacific, the first major one since 1998. While the US-funded ocean-monitoring system is in a state of partial collapse
, the data has continued to grow stronger, and this may now be the largest ocean temperature anomoly ever seen
. A major El Niño could significantly boost global temperatures, cause severe weather and storms, melt Arctic sea ice and help push the world into a warm phase of the Pacific Decadal Oscillation, accelerating global warming. (more discussion

Scripps Institute of Oceanography projects that next month its monitoring station will for the first time measure CO2 at 400 parts per million.
Atmospheric CO2 has risen from 280 parts per million before the Industrial Revolution. 400 ppm is an arbitrary milestone that we'll blow right past on our way to 450 ppm within a few decades. This is an unprecedentedly fast rate of increase and it's getting faster. Not all measuring stations are exactly the same: A NOAA station in the Arctic measured CO2 at 400 ppm last year.

Wireless Emergency Alerts
(WEA) are a new service from U.S. weather service and FEMA. Starting in June, they will send a text message with a strange tone to your mobile device if you are in range of a Tornado Warning, Tsunami Warning or other major event (in the U.S. only). Major events include "Presidential Alerts." You do not need to sign up. Washington Post Capital Weather Gang

is a small uninhabited Caribbean island
74 km off the coast of Haiti. Both the US and Haiti claim sovereignty
over the island, though Haiti claims it in it's constitution
. Discovered in 1498 and explored in 1504 as part of Columbus's expedition when he became stranded on Jamaica and sent a canoe to Hispaniola
; the canoes ran into the island on the way and two Spaniards and several Indians who arrived on the island drank contaminated water killing most of the group
. The island was avoided until 1857 when it was claimed by the US as part of the Guano Islands Act
despite an earlier Haitian claim. Working conditions were very harsh on the island, manually moving over a ton guano from mines via rail cars to the landing point at Lulu Bay
which sacked the guano for transport on the S.S. Romance
. In 1889 the workers started a rebellion that killed several supervisors
and lead to a series of court cases
that affirmed the constitutionality
of the Guano Act. The island was abandoned in 1898 during the Spanish-American war forced the operator, Navassa Phosphate Company of Baltimore to file for bankruptcy
. In 1917 a lighthouse
was built since the island posed a hazard for ships entering the newly built Panama Canal. The island has remained uninhabited, save a few Haitian fishermen
that camp now and again, though it is highly coveted by amateur radio operators
seeking a DX
call-sign of KP1
. The island has been bounced around several federal
agencies until 1999
when the United States Fish and Wildlife Service
cataloged it as a National Wildlife Refuge
. In 2009 NOAA's Southeast Fisheries Science launched an expedition
to catalog the flora
and fauna of the reefs of the island, including a few feral cats roaming
on the island.
"Probably the most important conservation statute ever enacted into America’s fisheries law"
.. as of 2012, all 528 federally managed fish species now have imposed catch limits.
The US is arguably the first country in the world to do it. This means every species has a hard limit of how many fish can be taken - not just how many per-boat or angler - an absolute cap on the total number (actually by weight). The law was enacted in 2006 under a policy forged under President George W. Bush and finalized with President Obama's backing.(previously)

There are mysterious noises in the sea. NOAA has six unidentified underwater sounds
(and their kinda creepy spectrographs) on their website, recorded by the sonar arrays that used to hunt submarines, but which are now are used for research. The most famous of these is The Bloop
, a sound of seemingly biological origin
, yet many times louder than the loudest biolocial noise. With an origin in an empty stretch of the the Pacific Ocean, it gives Cthulhu watchers something to think about
. Another once-mysterious sound, The Boing
has been identified as coming from minke whales
. Yet the sounds known as Slow Down
, Julia, Train, and others
remain intriguing mysteries. [prev.]

Science & technology funding has an enormous long term impact on the economy, a fact that has not escaped China. Yet, Senators Ben Nelson (D-NE) and Susan Collins (R-ME) have proposed cutting
all National Science Foundation and Department of Energy Office of Science funding from the Senate American Reinvestment and Recovery Act
, along with almost all other proposed funding of the sciences and technological development, as a part of a $77.9B reduction effort. Why? Well, you'll notice that Nebraska & Maine don't contribute much to science & technology in the United States, nor win many grants, and hence no bacon for Nelson and Collins. [more inside]

"We were forced to evacuate the remotely operated vehicle, 'Jason II
,' several times to avoid getting it enveloped in volcanic clouds," said Bill Chadwick, ...one of the authors of the study. "But at other times, we could observe the eruption from only 10 feet away - something you could never do on land. So in some ways, we were able to see processes more clearly at the bottom of the ocean than we ever could on land. That was surprising." From KGW

How Many Fish are in the Sea?
During the heady days of the late 19th century, in response to a perceived decline in coastal finfish stocks, Spencer Baird
and his clutch of young naturalists at the Smithsonian set out to find the answer. In 1871, Baird founded the U.S. Fish Commission
. The Comission set up operations in Woods Hole, MA,
where it continues its work today as the Northeast Fisheries Science Center
(a branch of NOAA’s National Marine Fisheries Service
). The Fish Census of 1880 established the fist benchmark on fish populations in coastal waters; crews of Gloucester schooners competed to see who could bring the most bizarre fish finds
up from the platueaus of the Grand Banks, and America’s first research vessel, the Albatross
, was purpose-built for the project. Baird's protege (and later successor) George Brown Goode
compiled the data into the first comprehensive reference work on American fisheries
. Known to students of salt water as “Goode’s Fisheries”, the report (beautifully illustrated
) remains invaluable to researchers today, as today's fish populations dip into an even more drastic decline.

The Ghost Nets: A New Kind of Pollution
What happens when a fishing boat loses a net on the high seas? No longer made of biodegradeable materials, these nets (which can be up to a mile long) drift freely through the oceans like needles in a haystack, trapping marine life
and damaging coral reefs. Now a team of NOAA working on the GhostNet 2005 project
has developed a computer model to help identify convergence zones
and locate these floating threats so cleanup can ensue. [Link to audio of NPR story about the project here
