For these reasons, systems and legislations have been put into place to further protect the marine park and its ecosystems and biodiversity, and to continue allowing for scientific research and public appreciation and education.

The environment, climate and location plays a key role in the activities, behaviours, survival and interactions of flora and fauna in Bremer Bay Marine Park, affecting whether the species in question is resident, migratory or otherwise.

[citation needed] The geomorphological construction of Bremer Canyon influences the currents and water movements, as well as upwelling of nutrients.

Currents also lead to the movement and transporting of tropical marine life from further afield; for example, the Leeuwin current is significant to the movements of southern bluefin tuna, Western Australia salmon and migratory humpback whales, as well as many species of coral, which, in their early stages of life, float in the water column until finding an appropriate location to attach and live.

In the Bremer Bay region, this nutrient increase fuels algal growth, and, in turn, benefits plankton and krill populations (predominantly through chlorophyll), which attract all the larger species to the area.

These invertebrates, inevitably, attract over 400 species of bony fishes, such as blue groper, herring and trevally, in addition to the aforementioned tuna and salmon.

There have been at least 40 species of elasmobranchs documented in these waters, including bronze whaler, great white, sand tiger, scalloped hammerhead, dusky, pencil, tiger, common blacktip, lemon, spinner, megamouth, gummy and blue sharks, bowmouth and white-spotted guitarfish, numerous rays and stingarees, as well as carpet sharks like the cobbler, western, dwarf spotted, floral-banded, gulf and spotted wobbegongs.

The defining features of the ecosystems food web include the apex predator being the orca, the keystone species being the squid and krill and the main primary producer being phytoplankton.

For example, scientists predict that global warming will decrease the abundance of phytoplankton (a keystone species in the Bremer Marine Park food web) in oceans.

Overfishing is also a major threat to marine ecosystems, since it can both wipe out populations and significantly pollute oceans through oil and fuel leakage.

[17] Bremer Bay contains two key ecological features being the ‘Albany Canyon group and adjacent shelf break’, and the ‘Ancient Coastline at 90-120 metres depth contour’.

The most prevalent steps and terraces can form large escarpments which can induce small upwelling events, which as previously mentioned cause higher abundance of marine life.

The Bremer Marine Park is specifically an ideal location for tourists due to its reputation to have high quantities of orca.

[citation needed] However tourism can also be a threat to biodiversity due to boats creation of underwater noise and fuel leakages.

[citation needed] From October 2016 to April 2017, numerous researchers set out to observe various species' interactions with both the biotic and abiotic environment.

[8] Specifically, scientists attempted to construct a food web showing the main interactions between species and their abiotic and biotic environment.

[8] Scientists in this investigation concluded that both ocean processes and human activity impacted food webs (as previously mentioned in this article, under 'marine life', 'threats to biodiversity' and 'tourism').

[8] From 2016 to 2020, scientists continued to collect data on orca populations, pelagic fish and abiotic factors (such as oxygen, chlorophyll a and temperature) in the Bremer Marine Park area.

[citation needed] In February 2021, the University of Western Australia published their findings on the deep-sea exploration of Bremen Canyon by the Schmidt Ocean Institute RV Falkor; scientists discovered significant deepwater coral gardens.
