Methods & Sampling

Zooplankton were collected using a multiple opening-closing net and environmental sensing system (MOCNESS) on R/V Roger Revelle cruise RR1813 during August-September 2018 (EXPORTS cruise). Onboard, zooplankton were wet-sieved into different size fractions using filtered seawater and 0.2, 0.5, 1.0, 2.0, and 5.0 mm mesh sieves and frozen at -20ºC. Zooplankton were dried and each fraction ground using a mortar and pestle. Samples were weighed and amino acids were isolated and purified by hydrolysis in 6N hydrochloric acid followed by cation exchange chromatography. The purified amino acids were then treated with isopropanol and trifluoroacetic acid yielding trifluoroacetic amino acid esters. The resulting solution was further purified by liquid-liquid extraction into chloroform before being stored in a dichloromethane-trifluoroacetic acid solution, and then finally transferred into ethyl acetate just prior to mass spectrometric isotopic analysis. CSIA-AA was carried out on a gas chromatograph coupled to an isotope ratio mass spectrometer (GC-IRMS), with all samples measured in triplicate when amino acid concentrations were sufficient.

MOCNESS

Supplied Name: Multiple opening-closing net and environmental sensing system (MOCNESS)

Supplied Description:

Multiple opening-closing net and environmental sensing system (MOCNESS) net with 1 m2 opening using 0.2 mm mesh plankton nets (see Wiebe, P. H., K. H. Burt, S. H. Boyd and A. W. Morton (1976) A multiple opening/closing net and environmental sensing system for sampling zooplankton. Journal of Marine Research 34:313-326.)

Instrument Type

Generic Name: MOCNESS

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0097/

Generic Description:

The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual) This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.
