MBARI’s Benthic Rover

November 14, 2014

The Monterey Bay Aquarium Research Institute's (MBARI) Benthic Rover is a subsea lab which methodically charts deep-sea carbon cycles. To measure metabolic activity in the sediment, twin respirometry chambers isolate samples of seafloor for 3 days at a time. Agitators stir up the sediment while sensors record oxygen levels. Diagram: Ken Smith, MBARI. The rover also has two optical/acoustic scanners that detect active chlorophyll and animals like worms buried up to 4 inches in the sediment. These two pieces of information help to fine-tune the respirometry measurements and to determine how quickly sediment arrives. At the MARS site 891 m (nearly 3,000 feet) below the surface, it’s always dark and there are no plants making food.

Pre-salt Seafloor Construction/Remote Operations Challenges Part 2

October 14, 2014

According to Petrobras production engineers, secondary recovery is increasingly being implemented to improve oil recovery in the pre-salt carbonates, where reservoir rocks are usually oil wet, and this characteristic affects the performance of water injection. Another problem concerning water injection is related to rock-fluid interaction, which is more important and complex in carbonates. In order to assess the risks involved, as well as to define mitigation actions, rock-fluid interaction tests are being carried out in the reservoir rock and the salt cap rock. Alternative recovery methods are being implemented in the pre-salt reservoirs.

CTD Sampling
CTD stands for conductivity, temperature, and depth, and refers to a package of electronic instruments that measure these properties. A device called CTD Rosette is lowered into the water and down to the seafloor to measure the salinity, temperature, depth and concentration of particles in the water column. A CTD device’s primary function is to detect how the conductivity and temperature of the water column changes relative to depth. Conductivity is a measure of how well a solution conducts electricity. Conductivity is directly related to salinity, which is the concentration of salt and other inorganic compounds in seawater. Salinity is one of the most basic measurements used by ocean scientists.
