Tropical Storm Lee – Flooding in New Orleans
September 3, 2011 | National Hurricane Center

Tropical Storm Lee is moving very slowly over southern Louisiana. That slow rate of movement will allow it to drop very large amounts of rain on New Orleans and surrounding areas.

“TROPICAL STORM LEE IS EXPECTED TO PRODUCE TOTAL RAIN ACCUMULATIONS OF 10 TO 15 INCHES OVER SOUTHERN LOUISIANA…SOUTHERN MISSISSIPPI…AND SOUTHERN ALABAMA THROUGH SUNDAY NIGHT…WITH POSSIBLE ISOLATED MAXIMUM AMOUNTS OF 20 INCHES. THESE RAINS ARE EXPECTED TO CAUSE EXTENSIVE FLOODING.” Quote from the National Hurricane Center.

Hurricane Irene – Category Two and Strengthening
August 22, 2011 | National Weather Service

Hurricane Irene is moving along the northern coast of the Dominican Republic. The National Weather Service reports:

“IRENE IS A CATEGORY TWO HURRICANE ON THE SAFFIR-SIMPSON SCALE. ADDITIONAL STRENGTHENING IS FORECAST DURING THE NEXT 48 HOURS…AND IRENE COULD BECOME A MAJOR HURRICANE ON TUESDAY.”

Hurricane Irene – Up to 20 Inches of Rain
August 22, 2011 | National Hurricane Center

Hurricane Irene is expected to drop heavy rain on the Caribbean area today and reach Florida later this week. The National Hurricane Center forecast from Monday morning includes:

“RAINFALL…IRENE IS EXPECTED TO PRODUCE TOTAL RAINFALL ACCUMULATIONS OF 5 TO 10 INCHES ACROSS PUERTO RICO…THE VIRGIN ISLANDS…THE DOMINICAN REPUBLIC…HAITI…THE SOUTHEASTERN BAHAMAS AND THE TURKS AND CAICOS ISLANDS.

Recovering Captain Henry Morgan’s Pirate Ship
August 8, 2011 | LA Times

After discovering six cannons believed to be part of Captain Henry Morgan’s pirate fleet, university and government researchers ran out of funds needed to sustain their marine archaeology work off the coast of Panama. However, Captain Morgan USA, the rum maker named after the 17th century pirate, kicked in enough money for a magnetometer survey and continued work.

Today’s Tides are Quite Different than Ancient Tides
August 4, 2011 | Oregon State University

“The ebb and flow of the ocean tides, generally thought to be one of the most predictable forces on Earth, are actually quite variable over long time periods, in ways that have not been adequately accounted for in most evaluations of prehistoric sea level changes.” Quoted from the Oregon State University news release.

Breaking Down the Deepwater Horizon Oil Slick
August 3, 2011 | Woods Hole Oceanographic Institution

“More than a year after the largest oil spill in history, perhaps the dominant lingering question about the Deepwater Horizon spill is, “What happened to the oil?” Now, in the first published study to explain the role of microbes in breaking down the oil slick on the surface of the Gulf of Mexico, Woods Hole Oceanographic Institution researchers have come up with answers that represent both surprisingly good news and a head-scratching mystery.” Quoted from the Woods Hole Oceanographic Institution news release.

Drought Relief for Texas from Tropical Storm Don?
July 28, 2011 | NASA

“Tropical Storm Don formed at 5 p.m. EDT last night, July 27, in the southern Gulf of Mexico and appears to be a small storm on GOES-13 satellite imagery. NASA compiled two days of GOES-13 imagery in a 30 second movie that shows how and where Don formed.” Quoted from the NASA news release.

Determining the Chemical Make-up of the Gulf of Mexico Plume
July 19, 2011 | Woods Hole Oceanographic Institution

Floodwaters Ruin Gulf of Mexico Oyster Crop
July 19, 2011 | MSNBC

Heavy flooding this spring and summer has pumped so much fresh water into the Gulf of Mexico that many oysters have died – they require salt water to survive. As a result the oyster harvest could be cancelled or restricted to give oyster populations a chance to recover. This will severely hurt businesses and employees involved in the harvest, processing and sale of oyster products.

Sediment From the Mississippi River Floods
June 30, 2011 | NASA Earth Observatory

“As the floodwaters swept over farms and towns in May and June 2011, they scoured fertilized soil from the ground and carried it downstream. Swollen rivers dumped thousands of tons of nutrients into the Gulf of Mexico, where they are forecast to cause a record “dead zone” this summer.” Quoted from the Earth Observatory image release.

Exxon: Huge Oil Discovery in the Gulf of Mexico
June 8, 2011 | Exxon Mobile @ Business Wire

Exxon Mobil Corporation announced a large oil discovery in the Gulf of Mexico, believed to be the largest in the past decade. Company geologists estimate that is has the potential for more than 700 million barrels of recoverable oil equivalent.

Oil-Eating Microbes in the Gulf of Mexico Spill
April 25, 2011 | Woods Hole Oceanographic Institution

“In water from outside the slick, respiration rates were normal (that is, moderately low). In water from within the slick, respiration rates were about 10 times higher. The microbes were consuming oil at a very fast rate. But they also lacked nutrients….” Quoted from the WHOI press release.

Historical Bathymetry of the Mississippi-Alabama Coastal Region
April 25, 2011 | United States Geological Survey

Land loss and seafloor change around the Mississippi and Alabama barrier islands are of great concern to the public and to local, state, and federal agencies. USGS has published: “Historical Bathymetry and Bathymetric Change in the Mississippi-Alabama Coastal Region, 1847–2009″.

During & After: Gulf Coast Beaches Map
April 21, 2011 | National Geographic

National Geographic has a zoomable “during and after” map of the Gulf coast that shows the relative amount of oil that was observed on beaches during and after the Deepwater Horizon spill. Many of the beaches that had heavy to moderate oil now have only a trace if any oil observed. Data used to make the map was obtained from NOAA.

2,000 Year-Old Deep-Sea Black Coral in the Gulf of Mexico
April 20, 2011 | USGS

“For the first time, scientists have been able to validate the age of deep-sea black corals in the Gulf of Mexico.  They found the Gulf is home to 2,000 year-old deep-sea black corals, many of which are only a few feet tall. [...] Deep-sea black corals are a perfect example of ecosystems linked between the surface and the deep ocean. They can potentially record this link in their skeleton for hundreds to thousands of years.”  Quoted from the USGS press release.

2011 Hurricane Forecast
April 7, 2011 | Colorado State University

“Colorado State University researchers predicted that the 2011 hurricane season will have significantly more activity than average. They predict 9 hurricanes (compared to an average of 5.9) and 16 named storms (compared to an average of 9.6). The probability for one major hurricane (category 3, 4, or 5) tracking into the Caribbean is 61 percent, compared to an average probability of 42 percent. The probability for a major hurricane making landfall on the Gulf Coast is 47 percent, compared to an average of 30 percent.” Quote from the Energy Information Administration.
