Description

Diatom SEM images at 2 stations (11 & 22)

Methods & Sampling

Station 11 was collected on 160um mesh after being collected from the ROCA surface pump (impeller bilge pump) and flash frozen in seawater.

Station 22 was collected in 20um mesh from the underway system and flash frozen in seawater.

Instruments

Pump - Surface Underway Ship Intake

Supplied Name: Pump - underway ship intake

Supplied Description:

Instrument Type

Generic Name: Pump - Surface Underway Ship Intake

Acronym: Pump-Ship Intake

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/31/

Generic Description:

The 'Pump-underway ship intake' system indicates that samples are from the ship's clean water intake pump. This is essentially a surface water sample from a source of uncontaminated near-surface (commonly 3 to 7 m) seawater that can be pumped continuously to shipboard laboratories on research vessels. There is typically a temperature sensor near the intake (known as the hull temperature) to provide measurements that are as close as possible to the ambient water temperature. The flow from the supply is typically directed through continuously logged sensors such as a thermosalinograph and a fluorometer. Water samples are often collected from the underway supply that may also be referred to as the non-toxic supply. Ideally the data contributor has specified the depth in the ship's hull at which the pump is mounted.

Pump surface

Supplied Description:

The ROCA Surface Pump is a modified impeller bilge pump system that brings large volumes of surface seawater onto the deck of the ship for sampling and processing.

Instrument Type

Generic Name: Pump surface

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/31/

Generic Description:

A source of uncontaminated near-surface seawater pumped onto the deck of the research vessel that can be sampled and analyzed. This pumped seawater supply is from an over-the-side pumping system, and is therefore different from the vessel underway seawater system.
