0:00:10it's a busy at the office for scientific research vessel you have
0:00:17addition pull out all the stuff to learn all they can about large lakes on
0:00:23this july day they're applying the waters of lake superior
0:00:26there is wide impacts too large lakes like theory which is the most impacted
0:00:33the other hand the spectrum is like to pair is waters or mostly in pretty
0:00:38good shape
0:00:39geologists d colour there is the director the large lakes observe that for l a
0:00:44low at the university of minnesota duluth
0:00:47the support for the national science found
0:00:50scientist here study the biology chemistry physics and geology of lakes around the world
0:00:57here as the for much of the freshwater the plan
0:01:01as i started doing work to make sure i can realize that there have been
0:01:05very little
0:01:07in the way of scientific study explains the on the biology
0:01:13oceanography tom johnson helped establish the observatory in nineteen ninety four
0:01:18we see for example that might superior just one at a rate that surprises
0:01:25using tools like this robotic like this is just jane austen is gathering data on
0:01:30the long-term response of lake superior to climate change you also studies variations in i
0:01:36score one of things i'm very interested in his determining better when we changes here
0:01:42the reason why what happens impolite so
0:01:46we can watch tower
0:01:47the physics and biology of the weight change over time back and write my research
0:01:53teams also study side of it is like this one real from the bottom level
0:01:57like in mexico
0:01:59sediment to like the tape for as they relate the reported something about climate hydrology
0:02:06the energy of the like
0:02:09shortly after we've is it blue heron in bartender seventeen k excursion on lake superior
0:02:13your own here we focused on how what build up but i train is impacting
0:02:18their college you might say it's a great laboratory on a great like
