Herbivory Methodology

Microzooplankton grazing on phytoplankton, herbivory, was measured
using the dilution technique (1) as modified by Landry et al (2). The
modifications of this method provide a means of determining
microzooplankton grazing rates of phytoplankton as well as
phytoplankton growth rates. Experiments were performed on shallow
(5-10m) and deep (35-80m) water samples at the "long" stations. Water
was collected in 30L GoFlo bottles on the trace metal clean rosette.

Instruments

GO-FLO Bottle

Supplied Name: Go-flo Bottle

Supplied Description:

30L GoFlo bottles on the trace metal clean rosette were used to collect water.

Instrument Type

Generic Name: GO-FLO Bottle

Acronym: GO-FLO

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

GO-FLO bottle cast used to collect water samples for pigment, nutrient, plankton, etc. The GO-FLO sampling bottle is specially designed to avoid sample contamination at the surface, internal spring contamination, loss of sample on deck (internal seals), and exchange of water from different depths.

Trace Metal Bottle

Supplied Description:

Instrument Type

Generic Name: Trace Metal Bottle

Acronym: TM Bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.
