Whew!\u00a0 Hints at spring may finally be around the corner.\u00a0 Cold Arctic winter temperatures through most of the beginning of this new year have kept much of the\u00a0Great Lakes\u00a0in frozen repair\u00a0through early March.\u00a0\u00a0However,\u00a0a hopefull proxy for spring is showing itself in\u00a0the figure 1<\/strong> (18Z) loop (above)\u00a0and figure 2<\/strong> (close-up below) with the ongoing break-up ice ofver the last week or so.\u00a0Winds finally shifted from northerly to southwesterly,\u00a0helping to\u00a0lift <\/span>temperatures from\u00a0the region’s icy\u00a0continental grip with the mercury climbing into the lower 40s. Although the signal is welcome, there can be problems.\u00a0 The combination of shifting winds and warmer temperatures can bring hazardous conditions to the lake in the form of ice floes.\u00a0 For those who venture too far out when the break-up begins, there is a distinct change at becoming trapped and adrift on the ice…and headed towards Canada. \ufffd

\nIn the past, hundreds of ice fishermen\u00a0have been stranded on\u00a0huge ice floes\u00a0when the shifting winds caused\u00a0a floe to break away from the main ice.\u00a0 Some have even perished trying to escape (e.g. cold water and heart attacts, drownings, and being crushed by the ice itself).\u00a0\u00a0Many also lose expensive equipment to this phenomenon\u00a0– such as snowmobiles, trailers and fishing equipment.\u00a0 Most of those\u00a0who are rescued\u00a0are taken off by either helicopter\u00a0or hovercraft…and a lot of dollars.\u00a0\u00a0I<\/span>ce fishermen\u00a0often try to get as far out on the ice as they\u00a0can for the best\u00a0fishing…breaking many ice safety rules and put themselves in danger in the process.<\/span> Timely imagery from remote sensing sources\u00a0(like this MODIS group\u00a0of images) can\u00a0keep\u00a0(some) fishermen from becoming trapped, by\u00a0visually supporting (direct observation) the forecast\u00a0process that may indicate the the beginning of the ice break-up.\u00a0\u00a0Although this\u00a0MODIS imagerey\u00a0has great resolution (250m), it’s temporal resolution\u00a0could be better.\u00a0 When GOES-R finally arrive in the latter half of the decade, some of the resolution will be lost (500m), but the images will arrive every 5 minutes instead of once a day…so take your pick.\u00a0\u00a0\u00a0 <\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
