* In water columns or layers to about 100 m, 300 m, 90 m, and 300 m respectively, with exceptions noted; abbreviated as 
chlor., zoop., micro., and cop. respectively. G.M. means geometric mean. For further explanation see text and footnotes. 
1. Noon and night station positions were identical. 
2. No zooplankton haul was made at station 23; the value given is from an adjacent daytime station (25). 
3. Micronekton net was slightly torn during the haul. 
4. No zooplankton haul was made at station 98; the value given is from an adjacent night station (99). 
5. Night zooplankton and night copepods were estimated as in Appendix I because the haul was shallow. 
6. Same noon station was paired with two equally distant, physically similar, night stations.
