R: L4 plankton abundance time-series

L4.AllDates

R Documentation

L4 plankton abundance time-series

Description

This dataset is a plankton abundance time-series collected at the Western Channel Observatory L4 station. It contains zooplankton abundances in #/m^3, phytoplankton abundances in #/ml, and sea surface temperature in degrees C. Sampling dates for zooplankton, phytoplankton, and surface temperature values are not always aligned, resulting in NA values within the time-series.

Usage

data(L4.AllDates)

Format

A data frame with 1123 observations on the following 20 variables.

	`date`	sampling dates; often read into R as a factor variable
	`cnidarian`	e.g., hydromedusae and siphonophores
	`amphipod`	e.g., gammarids
	`chaetognath`	Sagitta spp.
	`krill`	Euphausiids (all stages)
	`pteropod`	Clione and Limacina
	`tunicate`	larvaceans
	`cladoceran`	Evadne spp. and Podon spp.
	`calanoid.lg`	large calanoid copepods (>2 mm)
	`calanoid.sm`	small calanoid copepods (<2 mm)
	`cyclopoid`	cyclopoid copepods
	`poecilostom`	poecilostomatoid copepods
	`harpact`	harpacticoid copepods
	`diatom`	phytoplankton: diatoms
	`dino`	phytoplankton: dinoflagellates
	`other.algae`	phytoplankton: e.g., coccolithophores, green
	`cirripedia`	meroplankton: barnacle nauplii and cyprids
	`mero.grazers`	meroplankton: other grazers, e.g., gastropod and bivalve larvae
	`decapod`	meroplankton: e.g., crab and shrimp larvae
	`surface.temp`	sea surface temperature (degrees C)
