Sole Eggs in the Bristol Channel

Description

Data on Sole Egg densities in the Bristol Channel (West Coast of England, UK.) The data are from 5 research cruises undertaken for the purpose of measuring Sole egg densities. Samples were taken at each of a number of sampling stations, by hauling a net vertically through the water column. Sole eggs were counted and assigned to one of four developmental stages.

Usage

data(sole)

Format

A data frame with 7 columns and 1575 rows. The columns are:
