Lava lamp tectonics: Research suggests giant blobs of subducted sediment float up through deep Earth
lava lamp structure subduction sediment earthcrust
2021/8/6
Sand and mud subducted off the coast of California around 75 million years ago returned to the Earth's crust by rising up through the mantle as enormous diapirs, like blobs in a lava lamp, new researc...
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. This basin hosts a number of back-ar...

Repeated Profiling of Microstructure Lenses with a Midwater Float
Microstructure Lenses Midwater Float
2009/3/7
A freely drifting, midwater float equipped with a buoyancy controller has been developed and used to obtain 20 m profiles of temperature gradient (0.02 m resolution) and temperature (0.5 m resolution)...
Gulf Stream Kinematics along an Isopycnal Float Trajectory
Gulf Stream Kinematics Isopycnal Float Trajectory
2009/1/12
An isopycnal-following float was deployed near the 400 m depth level in the high speed jet region of the Gulf Stream and tracked for approximately 300 km from the Blake Plateau towards Cape Hatteras d...
An Inverse Model of the North Atlantic General Circulation Using Lagrangian Float Data
Inverse Model Lagrangian Float Data North Atlantic General Circulation
2008/12/18
A nonlinear finite-difference inverse model is used for estimating the North Atlantic general circulation between 20° and 50°N. The inverse model with grid spacing 2° latitude and 2.5° longitude is ba...
Vertical Heat-Flux Measurements from a Neutrally Buoyant Float
Neutrally Buoyant Float net heat flux near-inertial critical layer
2008/12/10
A neutrally buoyant float instrumented to measure 1–5 m shear and stratification was deployed for ten days in a near-inertial critical layer at the base of a warm-core ring. Vertical velocity and temp...
Topographic Influences on Recirculation in the Deep Western Boundary Current：Results from RAFOS Float Trajectories between the Blake–Bahama Outer Ridge and the San Salvador “Gate”
deep western boundary current Blake–Bahama Outer Ridge Topographic Influences San Salvador “Gate”
2008/12/10
Over a period of several years, RAFOS floats were launched into three levels of the deep western boundary current (DWBC) east of the northern Bahamas in order to identify and study any local recircula...
Exchange Geometry Revealed by Float Trajectories in the Gulf Stream
Exchange Geometry Float Trajectories Gulf Stream
2008/12/3
In an effort to understand the extent to which Lagrangian pathways in the Gulf Stream indicate fluid exchange between the stream and its surroundings, trajectories of RAFOS floats are viewed in a fram...
Observations of pigment and particle distributions in the western North Atlantic from an autonomous float and ocean color satellite
Observations of pigment particle distributions western North Atlantic autonomous float ocean color satellite
2014/5/16
Profiling floats with optical sensors can provide important complementary data to satellite ocean color determinations by providing information about the vertical structure of ocean waters, as well as...
SOFAR Float Observations of an Intermediate-Depth Eastern Boundary Current and Mesoscale Variability in the Eastern Tropical Atlantic Ocean
SOFAR Float Observations Intermediate-Depth Eastern Boundary Current Mesoscale Variability Eastern Tropical Atlantic Ocean
2008/7/11
Two neutrally buoyant SOFAR floats vigorously looped and meandered at depths of 950–1150 m in the eastern tropical Atlantic Ocean. The float trajectories illustrate a poleward flow along the tropical ...

Monsoon effects in the Bay of Bengal inferred from profiling float-based measurements of wind speed and rainfall
Monsoon effects profiling float-based measurements
2014/4/18
Both rainfall and wind have acoustic signatures that can be discerned at depths in the ocean well below the sea
surface. We examine observations of rainfall and wind speed collected at a depth of 600...
