Convert EK60 data to echogram

Description

Convert imported EK60 raw data to class “echogram”.

Usage

ek2echogram(
  ekraw,
  frequency = 1,
  data = "Sv",
  environment = NULL,
  calibration = NULL
)

Arguments

ekraw	Imported EK60 data, as returned by read.EK60_raw.
frequency	An integer corresponding to index of the transceiver in the data to be converted.
data	A string indicating the desired data: acoustic backscattering strength (“Sv”) or target strength (“TS”).
environment	An optional list with two elements: “soundVelocity” and “absorptionCoeff” calculated according to sea temperature and salinity measured during data collection.
calibration	A list as above, with “gain” and “saCorr” obtained from the echosounder calibration.

Details

This function calls the sampleRange and convertPower functions to produce an object of class “echogram”.

Value

A vector with sample range (m).
