Sea No Evil – Disputes Arise Over North Carolina Sea Level Rise Bill
2012-06-04 13:16:48

Brett Smith for redOrbit.com The battle over climate change is heating up again this week with a proposed bill from North Carolina state legislators who are looking to ignore a rising sea level prediction for the sake of coastal economic development. A 2010 state-sanctioned panel report that predicts that a 1-meter rise in sea level by 2100 will threaten anything built along the Tarheel State´s low, flat coastline. Business group NC-20 has questioned the validity of the report,...

Climate variability associated with El Niño was associated with higher mortality for eggs and hatchlings of the critically endangered leatherback turtle, an effect that could be worsened by continuing global climate change, according to research published May 23 in the open access journal PLoS ONE. The El Niño Southern Oscillation brought dryer, warmer conditions to northwest Costa Rica, one of the major nesting sites in the area. The researchers, led by Pilar...

Continuing Deep Ocean Change In The Southern Ocean
2012-05-22 03:53:13

New research by teams of Australian and US scientists has found there has been a massive reduction in the amount of Antarctic Bottom Water found off the coast of Antarctica. Comparing detailed measurements taken during the Australian Antarctic program's 2012 Southern Ocean marine science voyage to historical data dating back to 1970, scientists estimate there has been as much as a 60 per cent reduction in the volume of Antarctic Bottom Water, the cold dense water that drives global ocean...

New Research On Seaweeds Shows It Takes More Than Being Flexible To Survive Crashing Waves
2012-05-10 12:58:48

Bladed and branched algae adapted to strong wave conditions are able to reconfigure their shape and size Seaweeds are important foundational species that are vital both as food and habitat to many aquatic and terrestrial shore organisms. Yet seaweeds that cling to rocky shores are continually at risk of being broken or dislodged from their holds by crashing waves with large hydrodynamic forces. So how do such seaweeds survive in intertidal zones? Do they have special properties that make...

Beachgoers In Peru Warned To Stay Away After Mass Pelican Die Offs
2012-05-08 04:36:42

Jason Farmer for RedOrbit.com The health ministry of Peru issued a warning recently to citizens and tourists to avoid beaches in Lima and north of the capital while investigators try to determine what may have caused the mysterious deaths of hundreds of pelicans. Peruvian officials say more than 538 pelicans and other types of birds have been found dead along the northern coast. The state-run news agency, TV Peru, puts the total number at an estimated 1,200 dead birds found along the...

GPS On Commercial Ships Could Improve Tsunami Warnings
2012-05-07 07:44:47

Commercial ships travel across most of the globe and could provide better warnings for potentially deadly tsunamis, according to a study published May 5 by scientists at the University of Hawaii — Manoa (UHM) and the National Oceanic and Atmospheric Administration's Pacific Tsunami Warning Center. James Foster, lead author and Assistant Researcher at the UH School of Ocean and Earth Science and Technology (SOEST), and colleagues were able to detect and measure the properties of the...

Greenland Glacier Acceleration Levels Less Than Originally Feared
2012-05-04 06:55:11

Some of Greenland's glaciers are moving approximately 30% faster than they were a decade ago, contributing to the rising sea level but not reaching worst-case speed levels that experts once feared, a new study published in Friday's edition of the journal Science has discovered. According to Reuters reporter Deborah Zabarenko, researchers at the University of Washington (UW) and Ohio State University (OSU) studied satellite data from 2000 to 2011. They focused on more than 200 glaciers and...

2010 Chile Earthquake Had Surprising Ecological Effects
2012-05-04 03:45:32

Long-forgotten coastal habitats reappeared, species unseen for years returned The reappearance of long-forgotten habitats and the resurgence of species unseen for years may not be among the expected effects of a natural disaster. Yet that's exactly what researchers found in a study of the sandy beaches of south central Chile, after an 8.8-magnitude earthquake and devastating tsunami in 2010. Their study also revealed a preview of the problems wrought by sea level rise--a major...

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...
