Notes

Caption from Oceanus magazine, Vol. 53, No. 2, pg. 38:
Graduate student Lauren Kipp measures radium-228 in the Arctic Ocean. The naturally occurring isotope is used to track the flow of material from land and sediments into the open ocean. Here, she removes a cartridge from a sampling instrument that collects chemical isotopes.
mage Of the Day caption:
Lauren Kipp, a graduate student in the MIT-WHOI Joint Program, spent 65 days on the U.S. Coast Guard icebreaker Healy in the summer of 2015, measuring levels of radium-228 across the Arctic Ocean. She found that levels of radiumtransported from shallow continental shelves by currents to the middle of the oceanhave almost doubled over the last decade. The surprising finding is evidence that rapid climate change is causing large-scale changes along the Arctic coast, which could also have significant impacts on Arctic food webs. Here, she tends to a sampling instrument that pumps seawater through the cartridges to collect chemical isotopes.
