Methods & Sampling

Seawater was collected in 30-liter Go-Flo bottles, except for a few stations sampled with CTD Niskin bottles. Community rate estimates were made by seawater dilution based on HPLC chlorophyll a values with flow cytometry corrections for changes in cell pigment. Full methods are described in:

BCO-DMO Processing

Version history:
Version 1:
Date 2001-03-13.
This version was previously labeled "final" but updates to the data were received on 2024-11-05.

Version 2:
Date 2024-11-07.
This version includes corrected growth rate estimates. The cited methods paper has also been updated.
BCO-DMO Processing Steps:
- Imported original file "AESOPS_bacterivory_BCO_DMO submission 5Nov2024.csv" into the BCO-DMO system.
- Imported 4 original herbivory files, "AESOPS_KIWI6 herbivory_revised.xlsx", "AESOPS_KIWI7 herbivory_revised.xlsx", "AESOPS_KIWI8 herbivory_revised.csv", "AESOPS_KIWI9 herbivory_revised.csv" into the BCO-DMO system.
- Concatenated the 4 herbivory data files into 1 data file, adding a column for cruise ID.
- Added the following columns to the herbivory data file from the bacterivory data file based on event numbers: Date, Longitude, Latitude.
- Converted Date column to YYYY-MM-DD format.
- Saved file as "2773_v2_herbivory_aesops.csv".

Instruments

Niskin bottle

Supplied Name: Niskin Bottle

Supplied Description:

CTD clean rosette (Niskin) bottles were used to collect water samples.

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.

Trace Metal Bottle

Supplied Description:

Trace metal (TM) clean rosette bottles were used to collect water samples.

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.
