On Saturday (February 7th), more than 130 fishermen were stranded off the Lake Eerie shoreline. Eerie is the fourth largest of the five Great Lakes, sandwiched between the Canadian province of Ontario and by the US States of Ohio, Pennsylvania, and New York. It is a freshwater lake, a very popular fishing destination. During winter, large areas of the lake freeze over, tempting fishermen to venture further from the coastline onto the ice floe.

However, over the weekend, tragedy struck when a large chunk of ice thinned and drifted from the Ohio coastline (along Crane Creek State Park‎). The ice floe broke away, carrying 135 fishermen into the lake. One 65 year old man fell into the freezing waters and died of a heart attack. The remaining 134 men had to be airlifted from the ice by the emergency services, some were stranded for several hours. For the full details of the rescue, read the Associated Press article.

Local officials warned fishermen of the risks with venturing too far into the frozen lake, but it would appear the temptation was too great to find the best fishing spot. According to news sources, the ice was up to 2 feet thick, giving the illusion of safety. However, temperatures were rising and an offshore wind of 35 mph cracked the ice, isolating the fishermen.

Having just explored the MODIS website for satellite imagery of the UK snow cover, I was contacted by David Gamey (at Mang’s Bat Page) wondering whether I had found any satellite imagery of the event. After a short investigation, sure enough the MODIS archives were up to date, showing the frozen Lake Eerie clearly.

Comparing two images (top), one from February 6th (the day before the ice floe breakage) and one from February 8th (the day after), it is clear there is significant thinning of the ice. In the Feb. 6th image, it is hard to see the lake at all, the ice blends very well with the surrounding land. On Feb. 8th, the blue of the lake water is highlighted signifying ice thinning and breakage.

It is striking how illustrative the MODIS photos are, providing valuable information about everything from snow cover to forest fires. This one example how a comparison between two dates of lake ice cover can be so valuable. I’ll be keeping a close eye on this Earth observing mission

Satellite View of UK Snow Storms

UPDATE: This post is from the snowstorm in February 2009, for the satellite view of the UK in the grips of record low temperatures in January 2010 go to “UK Snow: Where Did My Hometown Go?

In case you were wondering what the recent snow storms in the UK looked like from space, NASA has released imagery from their Terra satellite for our viewing pleasure. The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument captured images down to a resolution of 250 metres/pixel, showing the detail in the snow cover and urban areas.

The MODIS on NASA’s Terra satellite captured this view of snow in England on February 4, 2009. The snow stretches from the English Channel north under a bank of clouds near the Scottish border. The winter storm that brought the snow in the first days of February blanketed southeast England with the heaviest snow the region had seen in 18 years, said BBC News. As much as 20 centimeters (8 inches) of snow fell on London. The poor weather closed transportation, schools, and businesses throughout southeastern England, reported BBC News.MODIS website

I know for a fact this huge amount of snow caused all sorts of inconvenience for the entire country, but I would have liked to have been in my hometown of Bristol (in the south-west–bottom-left–of the image above, under all that cloud cover) to experience a good old fashioned British winter. According to my mum, her street wasn’t lined in snow men, it was filled with snow giants, an entire town of them! Oh well, I’ll just have to admire the scene from space…
