Every day people on this ship say things so inspiring that I’m reminded why I love science. One student said people today always “think smaller” and are zooming in to closer, smaller scales, but that she loves “the global” and wonders why things on global scales, like the ocean, seem to have lost our attention. She will write more about her inspiration and work later in the blog, but for now I’m learning so many things as she and other students continue to share their work. Here are a couple more that I hope inspire you too.
Alena (who is from Russia) talked about how water masses from different places, like the Arctic or Atlantic, each have a “fingerprint” of unique chemical, physical, and biological characteristics. When the mooring detects changes from one depth to another, it is detecting a separate water mass. If it detects changes over time at a certain location/depth, it means there were changes in conditions at the origin of the water mass (even if it was 1000 years ago or an ocean away). And this applies worldwide, from the Arctic to Miami and back again.
Meri (who is from Finland), told us about the two water currents from the North Atlantic Ocean. These two “branches,” the Barents Sea Branch and Fram Strait Branch, enter and are distributed around the Arctic, partially mixing with each other and other Arctic waters. This massive mixing mostly occurs north of the shallow Kara and Laptev Seas, and causes changes in temperature and salt content. This is one of the reasons why our ship is there as we speak.
Here Alena and Meri are in the ship’s hangar (imagine a helicopter fitting in here) learning about components of the instruments that will go into the ocean and tell us even more about these global effects.
