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...

Natural disasters like earthquakes and tsunamis are expected to have substantial ecological effects, but if researchers don't have enough data about the environment before the disaster strikes, as is usually the case, it is difficult to quantify these repercussions. The 2010 earthquake and subsequent tsunami in Chile is a rare exception to this trend, and researchers were able to conduct an unprecedented report of its ecological implications based on data collected on coastal ecosystems...

First-Of-Its-Kind Study Reveals Surprising Ecological Effects Of Earthquake And Tsunami
2012-05-03 06:29:33

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 have found on 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 symptom of climate change. In a scientific first, researchers from Universidad...

Old Maps And Dead Clams Help Solve Coastal Boulder Mystery
2012-05-01 08:09:26

Perched atop the sheer coastal cliffs of Ireland's Aran Islands, ridges of giant boulders have puzzled geologists for years. What forces could have torn these rocks from the cliff edges high above sea level and deposited them far inland? While some researchers contend that only a tsunami could push these stones, new research in The Journal of Geology finds that plain old ocean waves, with the help of some strong storms, did the job. And they're still doing it. The three tiny Aran...

Tragedy Of Titanic Can Now Be Avoided Thanks To New Tracking Systems
2012-04-14 04:53:57

This weekend marks a century since the RMS Titanic struck an iceberg while crossing the North Atlantic, taking 1,500 lives down to the bottom of the sea with it. Now, technology has paved the way for disasters like Titanic to be avoided, such as the International Convention for Safety of Life at Sea and the International Ice Patrol (IIP). The IIP monitors icebergs and establishes an iceberg danger area based on observations that are being fed into drift and melt models. The Ice...

Indonesian Earthquake: Update
2012-04-11 08:37:20

Lawrence LeBlond for RedOrbit.com Wednesday´s powerful 8.6-magnitude earthquake that struck off Indonesia´s western coast at 2:38 p.m. local time, was followed by fears of a tsunami, gripping a region that still had the 2004 tsunami -- one that ravaged numerous coastal communities along the Indian Ocean and killing more than 230,000 people -- fresh in their minds. But hours after the fears of a tsunami subsided, a strong 8.2-magnitude aftershock hit the region sparking a new...

8.7 Earthquake Prompts Tsunami Warnings For Indian Ocean Coastlines
2012-04-11 05:33:00

Lawrence LeBlond for RedOrbit.com A tsunami warning has been issued for the entire Indian Ocean on Wednesday April 11 after a massive 8.7 magnitude earthquake off the coast of Indonesia at 2:38 p.m. local time (3:38 a.m. EST) sent residents around the region out of their homes and offices in fear. The US Geological Survey (USGS) said the temblor was centered 20 miles beneath the ocean floor, a little more than 300 miles from the provincial capital of Banda Aceh. The quake put emergency...

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...

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...
