Facilities for in vivo studies include two large experimental aquarium rooms. Hubbs Hall experimental aquarium facility is 2751 square feet with 12 trays and 30 tanks (most insulated) of volumes ranging from 1020 l to 7560 l, utilizing an 'open seawater system' that can deliver chilled (8 deg C), ambient (12 deg C-21 deg C), and warm (28 deg C) seawater . Chilled and warm seawater temperatures are very reliable, usually fluctuating no more then +/- 1 C deg. Four additional aquarium wet labs exist throughout Hubbs Hall, including a chilled 'closed system' in a controlled temperature room. The Ritter Hall Experimental Aquarium facility is 2150 square feet with 18 trays and 19 tanks with volumes ranging from 300 l to 21,000 l, a two chambered controlled light room and three each 3 m square cubicle rooms. Chilled (10 deg C) and ambient (12 deg C-21 deg C) seawater is also available via an 'open system'.
