Description

Methods & Sampling

Sampling was performed by HOV Alvin in the Gulf of Mexico using the following methods:
- Grab - using the claw of either port or starboard manipulator to pick up the sample
- Push core - used to collect sediment core samples, or invertebrates residing in the sediment
- Slurp - use of a vacuum system to collect sample from the seafloor or water column
