Seawater Facility

Seawater Facility


The Seawater Facility supports academic research and undergraduate teaching in environmental and life sciences. The facility is used by marine scientists at Macquarie University and their collaborative partners, to conduct controlled experiments and to house marine specimens.

Undergraduate students learning about the biology, chemistry and ecology of marine organisms are given the opportunity to get a closer look at live examples of marine plants and animals that are commonly seen and those that are often overlooked, in the Sydney Harbour region.

Seawater is collected from Sydney Harbour and then filtered to remove impurities before being added to a storage facility. Animals can be kept in a variety of conditions with temperatures ranging from 12 to 35°C (accuracy of +/-0.3°C), pH levels from 7.4 to 8.1 (accuracy +/-0.01) and a range of salinity levels.
