Variability In The Carbon Storage Of Seagrass Habitats And Its Implications For Global Estimates Of Blue Carbon Ecosystem Service, Paul Lavery, Miguel-Angel Mateo, Oscar Serrano, Mohammad Rozaimi Jan 2016

Variability In The Carbon Storage Of Seagrass Habitats And Its Implications For Global Estimates Of Blue Carbon Ecosystem Service, Paul Lavery, Miguel-Angel Mateo, Oscar Serrano, Mohammad Rozaimi

Research Datasets

The dataset compiles published data (in Lavery et al. 2013, PLoS ONE 8(9): e73748. doi:10.1371/journal.pone.0073748) on biogeochemical variables (organic matter, organic carbon and CO3 contents, and stable carbon isotope signatures of the organic carbon) in sediment core from seagrass meadows in Australia. The cores studied were up to 29 cm long, and ecompass tropical, subtropical and temperate seagrass meadows in intertidal and subtidal habitats.


Increasing Sediment Accumulation Rates In La Fonera (Palamós) Submarine Canyon Axis And Their Relationship With Bottom Trawling Activities, P. Puig, J. Martin, P. Masque, A. Palanques Jan 2015

Increasing Sediment Accumulation Rates In La Fonera (Palamós) Submarine Canyon Axis And Their Relationship With Bottom Trawling Activities, P. Puig, J. Martin, P. Masque, A. Palanques

Research outputs 2014 to 2021

Previous studies conducted in La Fonera (Palamós) submarine canyon (NW Mediterranean) found that trawling activities along the canyon flanks cause resuspension and transport of sediments toward the canyon axis. 210Pb chronology supported by 137Cs dating applied to a sediment core collected at 1750m in 2002 suggested a doubling of the sediment accumulation rate since the 1970s, coincident with the rapid industrialization of the local trawling fleet. The same canyon area has been revisited a decade later, and new data are consistent with a sedimentary regime shift during the 1970s and also suggest that the accumulation rate during the last decade …


Millennial Scale Impact On The Marine Biogeochemical Cycle Of Mercury From Early Mining On The Iberian Peninsula, Oscar Serrano Gras, A. Martinez-Cortizas, M. A. Mateo, H. Biester, R. Bindler Jan 2013

Millennial Scale Impact On The Marine Biogeochemical Cycle Of Mercury From Early Mining On The Iberian Peninsula, Oscar Serrano Gras, A. Martinez-Cortizas, M. A. Mateo, H. Biester, R. Bindler

Research outputs 2013

The high-resolution mercury record of a Posidonia oceanica mat in the northwest Mediterranean provides an unprecedented testimony of changes in environmental mercury (Hg) loading to the coastal marine environment over the past 4315 yr BP. The period reconstructed made it possible to establish tentative preanthropogenic background Hg levels for the area (6.8!1.5 ng g–1 in bulk sediments). A small, but significant, anthropogenic Hg increase was identifiable by ~2500 yr BP, in agreement with the beginning of intense mining in Spain. Changes in the record suggest four major periods of anthropogenic Hg pollution inputs to the Mediterranean: first, during the Roman …


Meta-Analysis Reveals Complex Marine Biological Responses To The Interactive Effects Of Ocean Acidification And Warming, Ben P. Harvey, Dylan Gwynn-Jones, Philippa J. Moore Jan 2013

Meta-Analysis Reveals Complex Marine Biological Responses To The Interactive Effects Of Ocean Acidification And Warming, Ben P. Harvey, Dylan Gwynn-Jones, Philippa J. Moore

Research outputs 2013

Ocean acidification and warming are considered two of the greatest threats to marine biodiversity, yet the combined effect of these stressors on marine organisms remains largely unclear. Using a meta-analytical approach, we assessed the biological responses of marine organisms to the effects of ocean acidification and warming in isolation and combination. As expected biological responses varied across taxonomic groups, life-history stages, and trophic levels, but importantly, combining stressors generally exhibited a stronger biological (either positive or negative) effect. Using a subset of orthogonal studies, we show that four of five of the biological responses measured (calcification, photosynthesis, reproduction, and survival, …

The Hillarys Transect (1): Seasonal And Coss-Shelf Variability Of Physical And Chemical Water Properties Off Perth, Western Australia, 1996-98, Alan F. Pearce, M J. Lynch, Christine E. Hanson Apr 2006

The Hillarys Transect (1): Seasonal And Coss-Shelf Variability Of Physical And Chemical Water Properties Off Perth, Western Australia, 1996-98, Alan F. Pearce, M J. Lynch, Christine E. Hanson

School of Natural Sciences Publications

A 27-month study of the water properties across the continental shelf off Perth, Western Australia (the "Hillarys Transect") has provided the first systematic inter-disciplinary climatology of the physical, chemical, optical and biological cycles across the shelf. This paper describes the main features of the seasonal and cross-shelf variability of the physical oceanography and chemistry, while companion papers discuss some of the links between the biology and physics of the region

Visualisation Of Inshore Marine Water Depth Data, Karen Powell Jan 1994

Visualisation Of Inshore Marine Water Depth Data, Karen Powell

Theses : Honours

The literature review performed as part of this Project concentrated on two objectives. The first objective was the identification of techniques applicable to the visualisation of the inshore marine water depth data obtained from the Department of Marine & Harbours (M&H). The second objective involved examining how colour is best used within data visualisation. The experimentation investigated a simple method for interpreting movement between depth surveys undertaken by M&H. Although it achieved the objective of creating a longer and smoother animation, it was concluded that the movement of the harbour floor was not accurately represented. The Project applied an optical …
