Sinopsis
Excerpt from Collecting and Processing Data on Fish Eggs and Larvae in the California Current Region
The original lines of the pattern were based on line 80 off Point Conception, and set parallel to that line 120 miles apart, north to line 10 off the United states-canadian border, and south to line 120 off Point Eugenia, Baja California. They were plotted to extend 30° southwest of lines of latitude, thus perpendicular to the coast of central California, north of Point Conception. It was intended that the 120-mile spacing would allow for additional lines to be plotted 12 miles apart between the cardinal lines and still be designated by whole numbers with out resorting to fractions. However, when lines were added between cardinal lines, it was deemed sufficient to space them at 40-mile intervals. Thus, the major pattern consists of the cardinal lines in multiples of 10 ending in o's and the or dinal lines ending in 3's and 7's. During the course of the investigations, lines were added finally to include line 157 just south of Cape San Lucas, Baja California.
The stations on the lines were laid out on the basis of a perpendicular to line 80, at a point designated station The perpendicular, through all lines parallel to line 80, aligned the stations designated as 6o's.

Excerpt from Collecting and Processing Data on Fish Eggs and Larvae in the California Current Region
A vessel used to collect oceanographic data should be a relatively stable platform at sea and be capable of reasonably rapid coverage of large areas for long periods of time. Today, most ves sels used for biological and hydrographic re search ou the high seas are 100 or more feet long, powered to cruise at 10 to 15 knots, and capable of staying at sea for 14 to 30 days. Some ships are of multipurpose design in that they can col lect plankton and hydrographic data and convert to fishing operations to handle large fishing nets, trawls, seines, etc.
Gear common to the collections of plankton and hydrographic data are power winches equipped with high-strain wire, an over-the-side platform for handling gear clear of the ship's side, and a weight at the end of the wire. Ship board facilities should include sheltered spaces for laboratory work and adequate storage spa ces for gear and samples.
