Bringing the Vibe Down from Ten to Zero: Effects of Glacial Discharge on Northern Rockweed in the Gulf of Alaska
Arctic glacial estuaries are unique and extremely dynamic maritime ecosystems, being simultaneously influenced by tidal action, oceanic currents, and terrestrial glacial meltwater. Since glacial melt and recession due to anthropogenic climate change are expected to accelerate, understanding how glac...

Arctic glacial estuaries are unique and extremely dynamic maritime ecosystems, being simultaneously influenced by tidal action, oceanic currents, and terrestrial glacial meltwater.
