Earthquake In British Columbia Leads To Tsunami Warnings
2012-10-28 07:07:05

redOrbit Staff & Wire Reports - Your Universe Online A magnitude 7.7 earthquake struck the Canadian province of British Columbia late Saturday night, leading to short-lived tsunami warnings and mass evacuations as far away as Hawaii, according to various media reports. The earthquake was centered in the Queen Charlotte Islands area (also known as Haida Gwaii) of British Columbia, US Geological Survey (USGS) officials told Mark Thiessen and Oskar Garcia of the Associated Press (AP),...

El Nino Event “Failure to Launch” Andover, MA (PRWEB) October 23, 2012 WSI (Weather Services International) expects the November-January period to be cooler-than-normal across the northwestern quarter of the country and in parts of the Southeast, with above-normal temperatures across most of the eastern two-thirds of the country. The WSI seasonal outlooks reference a standard 30-year normal (1981-2010). “It is now clear that the previously expected El Nino event is dead...

Atlantic Heat Pump Was Once Faster
2012-10-16 13:39:01

April Flowers for redOrbit.com - Your Universe Online A new study from an international team of scientists led by environmental physicists at Heidleberg University in Germany suggests that the circulation of the Atlantic Ocean was faster during the last Ice Age than today. It has long been assumed that heat transport in the Atlantic Ocean during the last Ice Age was weaker, but according to the new data, it appears that it was actually stronger than it currently is. The team used...

Scientists and flight crew members with Operation IceBridge, NASA's airborne mission to study Earth's changing polar ice, are beginning another campaign over Antarctica. Now in its fourth year, IceBridge's return to the Antarctic comes almost a year after the discovery of a large rift in the continent's Pine Island Glacier. The first science flight of the campaign began Friday at 8 a.m. EDT when NASA's DC-8 research aircraft left Punta Arenas, Chile, for an 11-hour flight that will take it...

Sea Rise Will Be Irreversible Over Next Several Thousand Years Due To Greenhouse Gas Emissions
2012-10-02 15:25:24

Brett Smith for redOrbit.com - Your Universe Online A groundbreaking study by a team of European researchers warns that greenhouse gas emissions will cause an irreversible rise in sea level over the next several thousand years. The study, published in the latest edition of the journal Environmental Research Letters, expanded the scope of typical climate change studies to include thousands of years in its projections and also took into consideration all of the Earth´s land ice,...

A Better Look At Salinity From SMOS
2012-10-01 08:26:12

Earth observation measurements shouldn´t be taken with a pinch of salt. ESA is comparing readings of sea-surface salinity from drifting floats to confirm the SMOS water mission´s measurements. Since its launch in 2009, ESA´s Soil Moisture and Ocean Salinity (SMOS) satellite has been helping us to understand the water cycle. As with any Earth observation mission, it is important to validate the readings acquired from space. This involves comparing the satellite data with...

'20 Years Of Progress In Radar Altimetry Symposium' Gains Altitude In Venice
2012-09-24 10:41:43

Scientists have gathered in the 'floating city' this week to talk about radar altimetry — measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors. Held every five years, the '20 Years of Progress in Radar Altimetry Symposium' gives participants the opportunity to focus on the challenges overcome to develop our current understanding of Earth´s surface variations observed by altimetry. Radar altimeters record the surface...

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...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
