Enhanced Viral Activity in the Surface Microlayer of the Arctic and Antarctic Oceans

Microorganisms, 2021
The ocean surface microlayer (SML), with physicochemical characteristics different from those of subsurface waters (SSW), results in dense and active viral and microbial communities that may favor virus–host interactions. Conversely, wind speed and/or UV

Isolating the signal of ocean global warming [PDF]

, 2007
Identifying the signature of global warming in the world's oceans is challenging because low frequency circulation changes can dominate local temperature changes.

Interior–atmosphere coupling on TRAPPIST-1f, g, and h: cryovolcanic water exospheres and infrared detectability

Astronomy & Astrophysics
Aims. We investigate the interior structures and cryovolcanic observability of the exoplanets TRAPPIST-1f, g and h. Our aim is to determine which interior configurations can sustain subsurface liquid water oceans in thermal equilibrium and to assess ...

Spectroscopic detection of a ubiquitous dissolved pigment degradation product in subsurface waters of the global ocean [PDF]

Biogeosciences, 2012
Measurements of light absorption by chromophoric dissolved organic matter (CDOM) from subsurface waters of the tropical Atlantic and Pacific Oceans showed a distinct absorption shoulder at 410–415 nm.

Key Technologies and Instrumentation for Subsurface Exploration of Ocean Worlds [PDF]

Space Science Reviews, 2020
AbstractIn this chapter, the key technologies and the instrumentation required for the subsurface exploration of ocean worlds are discussed. The focus is laid on Jupiter’s moon Europa and Saturn’s moon Enceladus because they have the highest potential for such missions in the near future. The exploration of their oceans requires landing on the surface,

Do tidally-generated inertial waves heat the subsurface oceans of Europa and Enceladus? [PDF]

, 2019
Some of the moons of the outer solar system harbour subsurface liquid oceans. Tidal dissipation plays an important role in preventing these oceans from freezing.
