R: Hydrographic section

section {oce} | R Documentation

## Hydrographic section

### Description

This is line A03 (ExpoCode 90CT40_1, with nominal sampling date 1993-09-11). The chief scientist was Tereschenkov of SOI, working aboard the Russian ship Multanovsky, undertaking a westward transect from the Mediterranean outflow region across to North America, with a change of heading in the last few dozen stations to run across the nominal Gulf Stream axis. The data flags follow the "WHP Bottle"convention, set by `initializeFlagScheme,section-method()` to `"WHP bottle"`. This convention used to be described at the link `https://www.nodc.noaa.gov/woce/woce_v3/wocedata_1/whp/exchange/exchange_format_desc.htm` but that was found to fail in December 2020.

### Usage
