Restoration reduces sea-level rise impacts over next 100 years A new study, led by PRBO Conservation Science (PRBO), projects a bleak future for San Francisco Bay's tidal marshes under high-end sea-level rise scenarios that are increasingly likely. PRBO and colleagues found that in the worst case scenario 93% of San Francisco Bay's tidal marsh could be lost in the next 50-100 years [with 5.4 feet or 1.65 meters of sea-level rise, low sediment availability and no significant restoration]....

Image 1 - Rethinking The Ocean's Role In Pacific Climate
2011-11-16 03:29:59

The new study can aid scientists in better understanding regional and global effects of climate change in the Pacific University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science researchers have climate scientists rethinking a commonly held theory about the ocean's role in the global climate system. The new findings can aid scientists in better understanding and predicting changes in the Pacific climate and its impacts around the globe. According to the study's lead...

Scientists Set Out On New 45-Day Deep-Sea Expedition
2011-11-07 12:43:57

Scientists set out on an expedition to explore the depths of the Indian Ocean on Monday from Cape Town. The researchers will embark on a 45-day research cruise exploring areas where the deepest sea creatures lie. Aurelie Spadone, a sea specialist with the International Union for Conservation of Nature (IUCN) who is among the scientists, said "it would be very surprising if we don't come back with a new species." The mission is the second to visit the seamounts along the South-West...

Operation IceBridge: Watching The Birth Of An Iceberg
2011-11-03 04:41:08

[ Watch the Video ] After discovering an emerging crack that cuts across the floating ice shelf of Pine Island Glacier in Antarctica, NASA's Operation IceBridge has flown a follow-up mission and made the first-ever detailed airborne measurements of a major iceberg calving in progress. NASA's Operation Ice Bridge, the largest airborne survey of Earth's polar ice ever flown, is in the midst of its third field campaign from Punta Arenas, Chile. The six-year mission will yield an...

Image 1 - Debris Field From Japan’s Tsunami To Hit US Next Year
2011-10-26 04:49:09

An estimated 5 million to 20 million tons of debris now floating in the ocean following Japan's massive tsunami is due to hit the shores Hawaii by early next year, before reaching the U.S. West coast sometime in 2014, according to estimates by University of Hawaii scientists. The projections have been validated by a Russian training ship, which spotted the debris in the Pacific Ocean where the scientists from the university's International Pacific Research Center predicted it would be....

Image 1 - 50-million-year-old Clam Shells Hint At Future Of El Niño Phenomenon
2011-09-20 04:44:31

  Earth warming will presumably not lead to a permanent El Niño state in the South Pacific Ocean. This is the conclusion drawn by an international team of researchers after it investigated 50-million-year-old clam shells and wood from the Antarctic. The growth rings of these fossils indicate that there was also a climate rhythm over the South Pacific during the last prolonged interglacial phase of the Earth´s history resembling the present-day interplay of El...

Sea levels, erosion top public concerns Europeans face greater risk of illness, property damage and job losses because of the impacts of climate change on the seas around them. Worried citizens, whose biggest related top-of-mind concerns are sea level rise and coastal erosion, are taking personal actions to reduce carbon emissions. However, they largely blame climate change on other groups of people or nations and assign governments and industry responsibility for mitigating the problem...

Image 1 - Argo Floats Help Monitor Ocean Acidity
2011-09-05 06:57:05

  Scientists can now remotely monitor the ocean´s changing chemistry with help from some of the five-foot-tall Argo floats that drift with deep ocean currents and transmit data via satellite back to land. A new and innovative method shows how readings of the acidity (pH) and total carbon dioxide (CO2) content of seawater can help scientists understand changes in the chemistry of the world´s ocean. A U.S.-based research team and their Canadian colleagues developed the new...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
