Biosecurity published reports

Biosecurity is the protection of the economy, environment and human health from the negative impacts of pests, weeds and diseases, including the management of invasive species if they become established (definition adopted by AusBIOSEC).

This requires steps to prevent the entry of harmful organisms, as well as the timely and efficient management of them if they do enter.

Biosecurity threats range from catastrophic diseases such as Foot and Mouth Disease, which causes rapid and widespread animal deaths, to more subtle and slower spreading problems such as invasive weeds, mussels that foul vessel hulls and fungus-induced dieback disease of trees. These …

Distribution Of The Hermit Crabs Clibanarius Vittatus And Pagurus Maclaughlinae In The Northern Indian River Lagoon, Florida: A Reassessment After 30 Years, Christopher J. Kelly, Richard L. Turner

Ocean Engineering and Marine Sciences Faculty Publications

The present distribution of two hermit crabs, Clibanarius vittatus and Pagurus maclaughlinae, was assessed for comparison with a study done more than 30 yr ago on decapods of the region. Clibanarius vittatus presently occurs in low or moderate density only at Sebastian Inlet. Retreat of C. vittatus from sites that it formerly occupied is attributed to intolerance of its larvae to low salinities recorded in the lagoon during recent reproductive seasons. Pagurus maclaughlinae remains the most abundant and widespread hermit crab in the lagoon. Its present distribution seems unchanged from the reference study despite prolonged periods, sometimes years, during which …

Combined Sustainable Biomass Feedstock Combustion, Co2/Eor, And Saline Reservoir Geological Carbon Sequestration In Northern Lower Michigan, Usa: Towards Negative Co2 Emissions, David Barnes, Robert Froese, R. G. Mannes, Brian Warner

Michigan Tech Publications, Part 1

This paper presents the results of a combined biomass combustion and geological carbon sequestration feasibility study in Northern Lower Michigan, USA related to a proposed solid fuel-fired 600 MW electric power plant, the Wolverine Clean Energy Venture (WCEV), near Rogers City, MI, USA. The biomass feedstock resource assessment, focused on low intensity, high diversity forest and agriculture in the proposed plant bioshed ( < 120 Km), has the potential to provide sustainable, dry biomass fuel well in excess of the maximum annual co-firing potential of 20% and offset as much as 1Tgy-1 of the estimated annual 5.1Tgy-1 of CO2 emissions (using 100% western coal). CO2/EOR potential in the Northern Niagaran Pinnacle Reef Trend is substantial. To date, seven reef reservoirs have been converted to CO2/EOR floods and three of these fields are sufficiently mature to project recovery efficiency in excess of 40% of primary oil recovery. Using these observations and historic oil production data CO2/EOR potential, in a region adjacent to a proposed CO2 pipeline originating from the plant site, is estimated to be at least 7.2 Mm3 (45 MMB) of incremental oil. Analysis of produced fluids in the same region indicates 55 Mmt of geological carbon sequestration (GCS) potential in abandoned oil and gas fields. GCS capacity is estimated at 271 Mmt in two, Paleozoic, saline reservoir targets providing a combined GCS (with abandoned oil and gas field GCS) of 326 Mmt in the pipeline study area. Estimated, combined, GCS in the proposed pipeline fairway alone is in excess of CO2 emissions for a hypothetical 50 year design life of the WCEV project burning 100% coal of 255 Mmt. Realization of biomass co-firing potential at 20% would result in a 50MMt offset of CO2 emissions during this 50 year period. Carbon capture and sequestration, including beneficial use in CO2/EOR, GCS in abandoned oil and gas fields, and saline reservoir GCS Sequestration at 90% of CO2 emissions from the proposed plant for a 50 year design life could result in the sequestration of 229.5 Mmt of CO2. These considerations support the potential for a net negative emissions profile of -24.5 Mmt for a hypothetical 50 year design life of the proposed WCEV project.
