>Where currents move slowly, the base of the ice looks like stacked ledges, **formed as melting eats away flats and leaves small steps**. In the fast outflow region, **currents create smoother surfaces with grooves**, where shear-driven turbulence, mixing caused by sliding water layers, drives rapid melting. Some pits are teardrop shaped, 984 feet long and 164 feet deep, carved by currents near the ice base. Elsewhere, the terraced plateaus probably record bursts of slightly warmer water entering the cavity, slowly peeling away layers of ice over many years.
Literally from the article you shared.

ET’s traverse our oceans and something involving one probably happened.

You’re pretty pumped about those warmer water currents melting the ice. I applaud it.
