Bottom current velocity can affect abundance and biodiversity of benthic fauna by altering disturbance regimes, changing available habitats, and regulating nutrient flows. The intermediate disturbance hypothesis predicts maximum biodiversity at a frequency of disturbance where recruitment is able to replace lost individuals but inter-specific processes don’t have time to exclude species (Connell 1978). Thus, highest biodiversity will be generally associated with occasional episodes of strong bottom current velocity (e.g.

Geomorphologic features are categorical descriptors of the shape of the seabed that range in scale from thousands of km2 (e.g. basins) to tens of m2 (e.g. sand waves, Heap and Harris 2008). Geomorphologic features themselves do not directly affect biodiversity, but since they are associated with depth, substrate hardness, current velocity, and productivity, they can be useful surrogates to link seabed structure and the distribution of benthic communities.

Chlorophyll-a can be estimated at continuous broad scales in the top layers of the ocean via satellite imagery (note this is different from chlorophyll-a in sediments). High primary productivity tends to promote low species richness and high evenness due to the ability of a few species to monopolise resources under ambient conditions (Snelgrove 2001, Hillebrand et al. 2007).

Depth is a consistently powerful explanatory variable in benthic studies (Gray 2001) due to its association with a range of other factors directly affecting abundance, biomass, and biodiversity (e.g. pressure, primary productivity, temperature). Shallow, eutrophic systems tend to have high biomass and low species richness due to high productivity but potentially stressful environmental conditions (Edgar 2001).

Native title is the recognition in Australian law that some Indigenous people continue to hold rights to their land and waters, which come from their traditional laws and customs.  It may include the right to possess and occupy an area to the exclusion of all others (often called a right of exclusive possession).

The Australian Government  developed its Indigenous Programs & Policy Locations (AGIL) dataset as an authoritative source of indigenous location names across Australia. It is designed to support the accurate positioning, consistent reporting, and effective delivery of Australian Government programs and services to indigenous locations.

The National Native Title Tribunal was established by the Native Title Act 1993 to make decisions, conduct inquiries, reviews and mediations, and assist various parties with native title applications, and Indigenous land use agreements (‘ILUAs’).

An Indigenous Land Use Agreement (ILUA) is an agreement about the use and management of land and waters made between people who hold, or may hold, native title in the area, and other people, organisations or governments. To be an ILUA, an agreement must meet with the requirements of the Native Title Act 1993.

Indigenous Protected Areas (IPAs) in Australia are voluntarily dedicated by Indigenous groups on Indigenous owned or managed land or sea country. They are recognised by the Australian Government as an important part of the National Reserve System, protecting the nation's biodiversity for the benefit of all Australians.
