Scientists anticipate that the fish community in the lagoons near Kaktovik, Alaska, Beaufort Sea, now includes more saffron cod (Eleginus gracilis) and larger saffron cod, like the one pictured here, given that the species has a higher thermal tolerance than many other co-occurring marine fishes.

Water pond in Halema‘uma‘u August 18, 2019. The water level continues to slowly rise in Halema‘uma‘u, drowning many of the small rocks that were previously exposed in the center of the pond. Ripples across the water surface were evident today.

This video sequence begins with a close-up of the fumaroles on the north side of Halema‘uma‘u, then widens to show a broader view of the crater, with the water pond at the bottom. The video then shows a close-up of the water surface, with steaming and ripples.

Before deploying the subbottom profiler for leg 2 of the Cape Cod Bay 2019 Survey, Wayne Baldwin, Alex Nichols, and Chuck Worley made sure that the floats are sufficiently inflated. In the relatively shallow waters of Cape Cod Bay we want the instrument towed at water's surface for the resolution of the sub seafloor geology.
