The Lau Basin Float Experiment (LAUB-FLEX) [PDF]
Oceanography, 2012 Before 2004, little was known about deep ocean circulation in the Lau Basin, a semi-enclosed basin in the South Pacific Ocean, about 1,500 km north of New Zealand.

The Iceland Deep Drilling Project 4.5 km deep well, IDDP-2, in the seawater-recharged Reykjanes geothermal field in SW Iceland has successfully reached its supercritical target [PDF]
Scientific Drilling, 2017 The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and

Numerical computation of hydrothermal fluid circulation in fractured Earth structures [PDF]
Geophysical Journal International, 1998 Summary Hydrothermal fluid circulation through porous Earth materials is an important physical phenomenon occurring in both submarine and continental environments. Irregularly interconnected discrete fractures are pervasive in nearly all Earth materials, providing preferential paths for fluid flow and controlling the circulating fluid patterns. Most

Numerical simulation of hydrothermal vent‐induced circulation at Endeavour Ridge [PDF]
Journal of Geophysical Research: Oceans, 2005 Hydrothermal venting at Endeavour Ridge is focused at five major vent fields spaced at ∼2‐km intervals along a narrow (∼1 km wide) north‐south trending rift‐valley. A Princeton Ocean Model with an axially symmetric rift‐valley centered within a rotating, full‐depth (2400 m) stratified ocean is used to simulate the circulation and associated temperature

Idealised modelling of ocean circulation driven by conductive and hydrothermal fluxes at the seabed
Ocean Modelling, 2018 Geothermal heating is increasingly recognised as an important factor affecting ocean circulation, with modelling studies suggesting that this heat source could lead to first-order changes in the formation rate of Antarctic Bottom Water, as well as a significant warming effect in the abyssal ocean.

Recent high-resolution mapping of Guaymas hydrothermal fields (Southern Trough)
BSGF - Earth Sciences Bulletin, 2018 Insights into the factors controlling fluid circulation through the crust and the nature of fluid venting at the seafloor are first steps in understanding their effect on ocean properties and climate change.
