A total of 22 stations, spaced at 10-mile intervals, were established in the Atlantic. In addition, three stations were regularly sampled j_n lower Chesapeake Bay. A detailed description of the study area and methods employed in collection of biological and hydrographic information is being published (Joseph, Massmann and Norcross, 1961). This report consists of a compilation of the various types of gear used in the collection of the plankton (T,s.bles 1, 2, 3). It seems advisable to distr·ibute this information because of impending changes in the survey area and in the collecting gear. Such a report also obviates the necessity of repetitious recounting of gea.r use in subsequent papers resulting from the plankton survey. The basic pattern of sampling consisted of 20-minute tows at 3 knots using surface and bottom gear. Meter Ol"' � meter nets were towed in pairs on the surface. Clarke-Bumpus nets were used to obtain surface and bottom samples, and the Gulf III was used for bottom tows during daylig·ht hours. Relative straining capacities of the various gears wr::re as follows: Clarke-Bumpus 1.0, Gulf III 10.4, � meter net 14.7, and meter net 63.9. Literature Cited Joseph, E. B., W. H. Massmann and J·. J.
