GO VISIONS MONITORING

The GO Visions™ technology has enabled Geo Oceans to set new standards in survey efficiency and data quality by performing a range of real-time data analysis and processing tasks in the field.

These improvements allow for the collection of larger quantities of higher quality processed data and creation of fine-scale habitat maps across large spatial areas far more accurately and time and cost efficiently than previously possible. The data can be collated with other habitat and bathymetry data to model and map the distribution of the marine habitats. The maps can be used to quantify the spatial area of the marine habitats and to monitor whether the distribution changes over time.

The GO Visions™ seabed monitoring package is used in conjunction with our various Mini ROV systems for quantitative assessments of percent cover and abundance to detect fine-scale changes within habitats, even those with sparse and patchy biota.

The GO Visions™ software processes semi-quantitative data in real-time to help guide decisions in the field and to check the data are suitable for the survey requirements. Back in the office we then analyse the data to generate quantitative statistics and reporting in an efficient manner.

The GO Visions™ technology has been successfully used to monitor marine habitats using transect, tagged coral and modelling methods on some of the world’s largest development projects.

Improve statistical power with GO Visions:

  • Real-time statistical data processing to check the data meets pre-defined conditions.
  • Production of fine-scale habitat maps (in real-time) to assist site selection.
  • Lower cost per sample means more replicates can be collected.
  • High spatial accuracy improves repeatability.
  • Operable in extreme conditions so exposed sites are not excluded.
  • Stereo images allows accurate size measurements.
  • Reduce variance between replicates.

PROJECT EXAMPLES

Benthic Marine Habitat Monitoring Survey

Big Bank Shoal is 560km offshore from Darwin in the Timor Sea. Geo Oceans chartered and managed a vessel contractor and mobilised to complete to support client environmental management objectives for the Buffalo Oil Field development. The team captured Geo Referenced high definition video footage, DSLR still images of the seafloor and GO Visions benthic marine habitat GIS data across all transects.

2019 Great Barrier Reef Towed Camera Survey

Geo Oceans’ marine scientists mobilised a towed camera and mini-ROV system, with USBL spatial positioning to the north east coast of Australia. The scope included acquisition of geo-referenced still images and HD video over several coral patches. The images were analysed for biota (e.g. coral, seagrass macroalgae) percent cover and substrate profile and type using the GO Visions software. The GO Visions data was displayed in Arc GIS software in real-time as point data overlaid on multibeam sonar data and was used to guide site selection and survey design during the campaign.

Dredging Benthic Marine Habitat Monitoring Program

This seagrass monitoring program was to support maintenance dredging operations in the approach channel to Cullen Bay marina in Darwin. Geo Oceans developed a monitoring program and conducted seagrass monitoring surveys prior to (baseline) and immediately after the dredging campaign to support with the environmental management of the project. Geo Referenced HD video footage, DSLR still images and GO Visions benthic marine habitat GIS data was collected across all transects in defined reference sites.

Brunei ROV Coral Survey

Geo Oceans completed an ROV coral monitoring survey for Shell in Brunei. The survey used GO ROV survey equipment combined with GO Visions marine habitat survey technology to capture spatially accurate HD video, still images and marine habitat data. A multi discipline team mobilised with an experienced ROV Supervisor, Marine Scientist trained in marine habitat surveys and ROV operations. Post field GIS software data analysis and mapping was performed, and a technical report was prepared and submitted to the client in order to support their environmental management of operations in the region.

Towed Camera Coral Survey - Asia

Geo Oceans was engaged to conduct a coral survey in the offshore Champion Field. The survey assessed the condition of the coral in the field prior to seismic investigations. The GO Visions TM towed camera system collected geo- referenced video, still imagery and data of coral habitats. The project acquired 20,567 points of qualitative habitat data and 7,612 still images across 44 transects over 4 days.

Decommissioning Program Bathymetric and Habitat Mapping

Geo Oceans were engaged to perform a bathymetric and habitat mapping survey prior to the arrival of construction vessels to the Airlie Island site. Proposed anchoring locations and safe approach channels were mapped and surveyed for sensitive marine habitats, raised features and bathymetry using Towed Camera and Multi Beam Echo Sounder systems.
