Marine Laboratory 

The Humboldt State University Marine Lab occupies a 16,200 square feet building overlooking the Pacific Ocean, near Trinidad Bay, Trinidad Beach, and Trinidad Headland. Specialized facilities include a culture room for larval invertebrates and algae, a wet lab for rearing marine invertebrates and fish for research, technical assistants with a complete shop for design and fabrication of experimental equipment. 

In addition to the standard biological and oceanographic laboratory equipment, other equipment includes UV-Vis double beam spectrophotometer, auto analyzer, gas chromatograph, liquid scintillation counter, various research microscopes including phase interference, inverted and polarizing, with digital still or video and 35mm photomicrography capabilities, video equipment, high speed refrigerated centrifuge, incubators, Ro-Tap sieve shaker, computer lab with T-1 line to the campus main frame and internet, pH meters, various analytical balances including an electro-balance, X-ray machine and numerous other items.

The seawater system supplies classrooms and numerous holding tanks ranging in size from 30 gallons to 1400 gallons. Seawater is pumped from Trinidad Bay into storage tanks above the Lab. The water is gravity fed to a sump then pumped through sand filters and chillers before entering the lab. The chillers maintain our seawater system at a constant 12°C (+/- 1°). Experiments requiring variations in temperature are accommodated by additional chillers or heaters.
