Description

RISE - Zooplankton - Euphausiid Growth Rates
The dataset contains measurements of growth rates of the euphausiids Euphausia pacifica and Thysanoessa spinifera.

Data collectors' identifying numbers, e.g., cruise and leg numbers, cast numbers
Rise cruises conducted aboard the R/V Wecoma are numbered sequentially: RISE 1W, RISE 2W, RISE 3W, RISE 4W, with the "W" for "Wecoma". There were concurrent RISE
cruises on the R/V Pt. Sur, hence the designation of the ship in the cruise name. Data in the spreadsheets associated with this metadata are identified by station
name. The station name is generally two letters and two numbers (eg: HR05) although some stations have only one letter (eg: P09) and some stations may have another letter following the numbers (eg: AC05c). The inclusion of a "0" in station names
with only one number was not followed consistently among different groups sampling
on the same cruises, so other data sets from these cruises (CTD, chl, nut, etc.) may
show a station name as P9 rather than P09. These differences in naming styles still
refer to the same sampling station.

Methods & Sampling

Dataset acquisition description

This dataset contains measurements of growth rates of the euphausiids
Euphausia pacifica and Thysanoessa spinifera. These data were
collected as part of the RISE project off Oregon and Washington, USA,
between 2004-2006.

Each line of data in each spreadsheet is a measurement of one individual animal and
includes cruise name, station name, date, latitude, longitude, and water depth.

These data were collected as part of the RISE project to look at vital rates of zooplankton
off of Washington and address the hypothesis that higher observed zooplankton biomass in
this area could be explained to some degree by higher growth and/or egg production rates
of the zooplankton.

Data parameter(s):

Euphausiid growth data is in units of millimeters of growth per animal per day.
This number may be negative since the animals sometimes get smaller after molting.

BCO-DMO Edits

- Some parameters renamed to conform to BCO-DMO convention

- Dates formatted to YYYYMMDD

- decimal data values padded to consistent decimal places

- Commas in Sex/Stage field converted to semi-colons

- Cruise changed from "RISE_1,2,3,4" to RISE04W1, etc for consistency with other data sets

Instruments

Bongo Net

Supplied Name: Bongo Nets

Supplied Description:

Instrument Type

Generic Name: Bongo Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/NETT0009/

Generic Description:

A Bongo Net consists of paired plankton nets, typically with a 60 cm diameter mouth opening and varying mesh sizes, 10 to 1000 micron. The Bongo Frame was designed by the National Marine Fisheries Service for use in the MARMAP program. It consists of two cylindrical collars connected with a yoke so that replicate samples are collected at the same time. Variations in models are designed for either vertical hauls (OI-2500 = NMFS Pairovet-Style, MARMAP Bongo, CalVET) or both oblique and vertical hauls (Aquatic Research). The OI-1200 has an opening and closing mechanism that allows discrete "known-depth" sampling. This model is large enough to filter water at the rate of 47.5 m3/minute when towing at a speed of two knots. More information: Ocean Instruments, Aquatic Research, Sea-Gear

Ring Net

Supplied Name: RingNet

Supplied Description:

Instrument Type

Generic Name: Ring Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic Description:

A Ring Net is a generic plankton net, made by attaching a net of any mesh size to a metal ring of any diameter. There are 1 meter, .75 meter, .25 meter and .5 meter nets that are used regularly. The most common zooplankton ring net is 1 meter in diameter and of mesh size .333mm, also known as a 'meter net' (see Meter Net).
