Kelly, S. J., Popova, E., Aksenov, Y., Marsh, R., & Yool, A. (2020). They Came From the Pacific: How Changing Arctic Currents Could Contribute to an Ecological Regime Shift in the Atlantic Ocean. Earth’s Future, 8 (4), e2019EF001394.
With a warming Arctic Ocean, it has been suggested that the ocean currents that connect the Pacific to the Atlantic may change. This could have potential biological consequences, including bringing Pacific species of plankton to the Atlantic. The authors investigated how the pathways bringing Pacific water to the Atlantic have changed, identify a pathway that takes less time that other routes to bring waters from Pacific to the Atlantic (but that is only occasionally available), and note that even the shortest timescales are over 2 years.
