marphy {pastecs}

Physico-chemical records at the same stations as for marbio

Description

The marphy data frame has 68 rows (stations) and 4 columns. They are seawater measurements at a deep of 3 to 7 m at the same 68 stations as marbio.

Usage

data(marphy)

Format

This data frame contains the following columns:

Temperature

Seawater temperature in °C

Salinity

Salinity in g/kg

Fluorescence

Fluorescence of chlorophyll a

Density

Excess of volumic mass of the seawater in g/l

Details

This dataset corresponds to a single transect sampled across the Ligurian Sea front in the Mediterranean Sea, between Nice (France) and Calvi (Corsica). The transect extends from the Cap Ferrat (close to Nice) to about 65 km offshore in the direction of Calvi (along a bearing of 123°). 68 regularly spaced measurements where recorded. They correspond to the stations where zooplankton was collected in the marbio dataset. Water masses in the transect across the front where identified as:

Stations 1 to 17

Peripheral zone

Stations 17 to 25

D1 (divergence) zone

Stations 25 to 30

C (convergence) zone

Stations 30 to 41

Frontal zone

Stations 41 to 46

D2 (divergence) zone

Stations 46 to 68

Central zone
