Towards a global strategy for the conservation of deep-sea active hydrothermal vents
No full textAbstract Deep-sea active hydrothermal vents are globally diverse, vulnerable, rare, remote, and isolated habitats, yet they face increasing threats from human activities, including deep-sea mining. To address the conservation challenges surrounding these habitats, we present a global assessment of the conservation status of deep-sea active vents. Our findings reveal that while 25% of the known deep active hydrothermal vents are currently under conservation interventions, only 8% benefit of full protection. These conservation interventions, consisting of area-based and regulation-based management measures, are implemented by 17 Sovereign States, three Regional Fisheries Management Organizations and one international treaty through 30 discrete interventions. However, our assessment and comparison of the specific measures for the 155 managed active hydrothermal vents reveal that the current conservation remain fragmented and discordant across jurisdictions and biogeographical provinces, resulting in overall insufficient protection, especially in Areas Beyond National Jurisdiction. Seizing the current momentum for ocean conservation, it is crucial to harmonize the management and protection of active deep-sea vents worldwide, taking into account their global biogeographic context and spatial distribution. This requires aligning current international initiatives that could improve baseline policies for the global protection of deep-sea hydrothermal vents
Spatial Tools and Analysis of WWII Shipwrecks
No full textThe sinking of thousands of ships during the Pacific Theater of World War II has blanketed the South Pacific region. These potentially polluting wrecks present a major environmental danger to the region in the form of oil spills and unexploded ordnance. As a major center of biological diversity, including World Heritage sites, the continued deterioration of these wrecks could destroy the rich marine life in these areas.
This study provides geospatial analysis of these wrecks, based on data from the United States and Imperial Japanese Navy. Wrecks have been mapped within ESRI GIS software and a variety of spatial and data analyses have been performed to address questions of environmental and geopolitical concern. A risk index has been developed to prioritize the most dangerous vessels. This index accounts for both characteristics of the ship, as well as the surrounding environment. Further, spatial tools have been designed to offer resource managers a basic method to predict sensitive ecosystems at risk from a wreck-based oil spill. For the first time, wreck data will be available for conservation groups and researchers to conduct their own risk planning.

Other Effective Conservation Measures in the Marine Environment: The Policy-Makers' Silver Bullet for Meeting Global Conservation Ambitions?
No full textThe concept of ‘other effective area-based conservation measures’ (OECMs) has recently gained traction, as they seem to offer an easier means to achieve area-based conservation targets than conventional protected areas, which can require greater stakeholder engagement, compromise and investment. Many existent area-based management measures – including traditional harvesting areas, indigenous sacred places and activity exclusion zones – may already offer some form of biodiversity protection, despite conservation not being their primary purpose, potentially meeting the OECM criteria. There is concern, however, that conferring OECM status to any such measure without consideration of all relevant aspects could result in an inflated sense of the proportion of area that is effectively protected. This paper investigates and reflects upon the legal basis of OECMs and assesses how governance frameworks may incorporate the concept to meet conservation commitments under the Convention on Biological Diversity and obligations under the United Nations Convention on the Law of the Sea
Social Context: A Review of Autobiography of a Disease
No full textAutobiography of Disease by Patrick Anderson thoroughly examines the author’s life threatening experience with Staphylococcus aureus (MRSA) osteomyelitis. Through notes kept by the author and caregiver/mother Anderson tells an evocative ethnography as told from the perspective of MRSA itself. This complex weaving of narratives highlights how multiple social and environmental considerations interact to impact Anderson\u27s experience with illness. This book may be of interest to anyone seeking to learn more about the social context of illness

Examining Space Use of Foraging Gray Seals (Halichoerus grypus) off the New England Coast
No full textThe Gray seal (Halichoerus grypus) is a highly migratory large phocid species occurring
in the waters of the Northeast Atlantic Ocean. After severe depletion during the 19th and 20th
century, this species has recolonized southerly US habitats around the Gulf of Maine (GOM) and
Cape Cod, resulting in increasing conflict with commercial fisheries that overlap with seal
foraging grounds. With uncertainty surrounding gray seal population dynamics as well as
methods for the management of this ecologically important protected predator, there is an
incentive to expand knowledge of gray seal feeding ecology, diet and foraging behavior to better
understand interactions between this species and economically profitable fishing sectors. This
study investigates gray seal foraging behavior off the coast of Cape Cod and throughout the
GOM. Examining data from 4 tagged individuals, this analysis implements a potential path
volume (PPV) methodology (Demšar and Long, 2019), to estimate space use in order to assess
the effect of sex and season on seal foraging volume. Additionally, a generalized additive model
(GAM) was used to predict species distribution and habitat suitability for a commercially
important gray seal prey item, Atlantic cod, to better understand potential spatial overlap
between commercial fisheries and foraging seals.
Results from PPV analysis shows highly variable space use by foraging seals, with
greater overall volumetric range during the Spring/Summer months. Spatial analysis of overlap
between foraging seals and predicted higher quality cod habitat was shown to vary by season.
The methodologies used in this study to assess overlap between commercially valuable fish
species and foraging gray seals have the potential to act as a valuable tool for managers and
fishers moving forward. Additionally, seal PPV is a useful metric to consider when evaluating
trends in foraging ecology of this species. Finally, the combination of the two methodologies
implemented in this paper might help shed light on recovery of vulnerable cod stocks
TRIBUTARY CREEK WATER QUALITY INFLUENCED BY LAND USE CHARACTERISTICS AT MARINE COPRS BASE CAMP LEJEUNE, NC
No full textMarine Corps Base Camp Lejeune is located in the flat coastal plains of North Carolina. The base is home to ecologically important and sensitive habitat. It is also the largest amphibious Marine Corps base with high impact training areas and a growing population. Creek water quality was monitored in ten tributary creeks throughout the base, representing paired plots of forested and developed drainage areas. It was my aim to assess land use contributions to creek nutrient concentrations.
By building watersheds using hydrology tools in ArcMap and a 1-meter horizontal resolution DEM, I was able to delineate watershed area and calculate land use proportions within each of the ten watersheds. In total, I defined twenty-two land use characteristics which were used as predictors of seven nutrient concentration response variables (TSS, NOx, NH4, PO4, ON, TN, Chla). Linear model results isolated significant predictors of water quality. For each response variable I fit the best GLM, indicated by StepAIC, using each predictor with a p-value less than 0.05. Nitrate/Nitrite (NOx) was best predicted by the percentage of paved roads within each watershed for annual averaged concentrations. When separated into storm and base flow events, NOx, again, is predicted by the percentage of paved roads. Ammonium (NH4) concentrations are correlated the percentage low intensity development which was defined by the National Land Cover Dataset (NLCD 2001).
These positive correlations make ecological sense and are consistent with similar land use studies. However, this study site is unique because of its low elevation, low flow accumulation, and lack of agricultural lands which are of high proportion in surrounding basins. It is important for base environmental managers to apply these results and models to answer the following type of question: How will creek water quality change if we convert one land cover type to another? Using the best model predicting NH4, I developed an interactive tool for managers to map out a proposed construction site and obtain changes in average NH4 concentrations in tributary creeks
