Larval Cycle of Crown-Of-Thorns Starfish (COTS)

The Great Barrier Reef (GBR) is currently experiencing a 4th wave of crown-of-thorns seastar (Acanthaster planci) infestations since the 1960’s. The seastars are spreading rapidly with reefs from Lizard Island to Cairns suffering massive coral mortality. The race is on again to learn more about the biology of COTS and fund some smart science to develop strategies that will minimise the coral loss caused by the voracious coral predator.

Green turtles Raine Island

Raine Island, a 27.5 hectare cay situated on a detached reef and located in the far northern Great Barrier Reef is, along with the adjacent Moulter Cay, the focus of approximately 90% of all nesting effort of the Northern Great Barrier Reef (NGBR) green turtle genetic stock. The small sand cay is the largest rookery in the world for the green turtle (Chelonia mydas) with upwards of 15 000 females having been recorded attempting to nest at the one time along the approximately 1.8km of beach.

Within a funding structure such as NERP TE, 'governance' is often described within the narrow framework of program roles and responsibilities. However there are benefits of considering the broader system of governance that such programs sit in, and in ensuring that each phase within the program cycle contributes to good governance outcomes. This broader idea of governance represents "the way society gets things done".

Visual fish census data collection AIMS reef monitoring
The Great Barrier Reef (GBR) has great economic importance as well as immense aesthetic value, contributing an estimated $5.8 billion to the Australian economy, principally through tourism, and commercial and recreational fisheries.

Screenshot of the Image Metadata Editor

The eAtlas Image Metadata Editor application is a Java program that allows information about the photos such as title, description, attribution, location, etc. to be recorded and saved in the images. When these images are then uploaded to the eAtlas this metadata is then maintained and displayed on the site. A web page is created for each image using the metadata added to the photo by the Image Metadata Editor. This application is intended to be used by eAtlas content administrators and those wishing to submit lots of photos to the eAtlas.

Data Report Form Preview

All datasets submitted to the eAtlas for publication need to complete an eAtlas dataset report form. This form is for collecting documentation on environmental research datasets and aims to ensure that these datasets can be reused in the future by others. The information collected in this report should address the key questions someone would have when trying to understand and use the associated dataset.

Seagrass
Seagrass meadows in Torres Strait are abundant and widespread. Seagrass/algal beds have been rated as the third most valuable ecosystem globally for ecosystem services. Their value is due to their diverse roles within marine coastal ecosystems. Like other plants seagrass harvest the sun’s energy and thus are a source of primary productivity; energy that can be passed through the marine food chain. Seagrass is a major food source for dugong, a marine mammal of high importance culturally and as food throughout the region.

Close up of bulk carrier ship from Torres Strait
A plethora of recreational and commercial vessels operate within or transit Torres Strait. They unite the island communities and are a key transport mechanism for all kinds of goods and services. While shipping offers many benefits to the Torres Strait there are also associated risks, especially in event of an accident. These include threats to water quality, biodiversity and ecosystem health, physical or chemical damage from groundings and the introduction of pests.

Dugong
Dugong (Dugong dugon) are air-breathing marine mammals of global conservation significance, that can grow up to three metres, weigh up to 400kg and live for at least 70 years. Females reach sexual maturity at six years, and produce a calf only once every 2.5-5 years thereafter. Gestation period is 14 months, but calves suckle milk from their mothers for 18 months after birth. Dugongs’ main food source is seagrass, but they also eat invertebrates such as worms, sea squirts, and shellfish.

Flood Plume from Fly River (Landsat 5)

The Torres Strait marine environment contains a relatively shallow (<20m) and highly productive stretch of seawater between the tip of Queensland and Papua New Guinea. It straddles the juncture of the Indian Ocean (Arafura sea) with the Pacific Ocean (Coral Sea), resulting in complex patterns of influence from the two ocean systems, including complicated tides and currents, and high biodiversity. Torres Strait contains over 100 islands, and a diversity of marine habitats including coral reefs, seagrass meadows, and rich benthic garden communities.

Torres Strait map
As part of Project 2.3 broadscale surveys and biodiversity assessments were conducted in the central island group and eastern island group within the Torres Strait region. Broadscale surveys were conducted by manta tow in February 2013 at Aureed Island Reef, Aukane Island Reef, Kabbikane Island Reef, Masig Island Reef, Mer Island Reef and Waier and Dauar Island Reef.
