The collection spans different regions within Australia, Malaysia, Timor Leste and Timor Sea region, Papua New Guinea, China, Thailand and Indonesia. Samples were collected from offshore, coastal and river areas, using a variety of methods over the timeframe. The data has contributed to studies in sediment mass balance in rivers, estuaries, deep water shelf and slopes to determine the environmental impact in tropical systems, nutrient budgets and dynamics. Research in both organic and inorganic carbon biomarkers and fluxes have developed carbon budget and carbon cycling dynamics for marine environments. The databases includes sediment descriptions of samples, measurements for geochemical mass balance, and analysis for trace elements including Aluminium, Carbon and Nitrogen and calculated ratios of Aluminium/Calcium, Carbonate Carbon and in some locations Arsenic and suspended sediment. Radiochemical analysis of some sediment core samples and surface water samples for natural isotopes of radium. Sampling equipment included Kasten Corer, Piston/Gravity Corer, Box Corer, Smith Macintyre Grab, Van Veen Grab, hand collection SCUBA, soil profile and Suspended Sediment samples, and sediment traps. {"type": "Polygon", "coordinates": [[[110.90820532869267, -24.45207284285571], [157.09961178017315, -24.45207284285571], [157.09961178017315, -3.4534147075551913], [110.90820532869267, -3.4534147075551913], [110.90820532869267, -24.45207284285571]]]} 110.90820532869267 157.09961178017315 -24.45207284285571 -3.4534147075551913 Deposition, mineralization and storage of carbon and nitrogen in sediments, Great Barrier Reef documentDigital Deposition, mineralization and storage of carbon and nitrogen in sediments, Great Barrier Reef HTML Sediment Mud Core Data documentDigital Sediment Mud Core Data CSV Sediment Surface Grab data documentDigital Sediment Surface Grab data CSV Using biomarkers to determine dispersion and cycling of organic matter from the Sepik River, Papua New Guinea documentDigital Using biomarkers to determine dispersion and cycling of organic matter from the Sepik River, Papua New Guinea HTML Tracing carbon cycling in the Gulf of Papua, Papua New Guinea, using organic biomarkers documentDigital Tracing carbon cycling in the Gulf of Papua, Papua New Guinea, using organic biomarkers HTML Sediment data from the Fly River Delta and Gulf of Papua, Papua New Guinea documentDigital Sediment data from the Fly River Delta and Gulf of Papua, Papua New Guinea HTML Sediment Data, Herbert River, north Queensland: 1987 - 2002 documentDigital Sediment Data, Herbert River, north Queensland: 1987 - 2002 HTML AIMS Web Site documentDigital audio/basic AIMS Web Site documentDigital audio/basic AIMS Web Site documentDigital audio/basic AIMS Web Site documentDigital audio/basic
