The document describes an automated system for mapping large areas of seabed habitats. It uses multibeam sonar to scan the seabed over areas of up to 10 square kilometers per day with resolution of less than 20 centimeters. The acoustic data is processed using specialized software that can automatically generate maps of seabed types within hours. The goal is to develop a modular system for integrating and processing data from multiple sensors to allow large-scale, cost-effective monitoring and classification of coastal habitats and seabed types.

Future work will enhance the model's accuracy and examine the effects of changing environmental conditions on lobster distribution.NASA HSI Workshop at UCSB 08/05/2008

The document discusses the challenges and advancements in coastal airborne hyperspectral imaging (HSI), particularly emphasizing the difficulties in imaging dark targets like water due to signal attenuation and lack of robust sensors. It highlights the capabilities of the SAMSON system, which provides high-quality HSI data and enables automated feature extraction for various applications, including environmental monitoring. The summary also stresses the need for standardized workflows and sensors to improve accessibility and demand for these technologies.Seagrass mapping and monitoring along the coast of Crete, Greece.

This mid-term MSc thesis presents research focused on mapping and monitoring seagrass meadows, specifically Posidonia oceanica, along the coast of Crete, Greece, using aerial and satellite imagery over a 10-year period. The study involves GIS and remote sensing techniques to assess the spatial distribution and environmental changes affecting seagrass meadows, based on primary data from fieldwork and secondary data from satellite sources. The objectives include detailed classification of seagrass distribution and analysis of the spectral reflectance to distinguish seagrass from other seafloor types.Seagrass Mapping and Monitoring Along the Coasts of Crete, Greece

The document is a research proposal focused on seagrass mapping and monitoring along the coast of Crete, Greece, specifically studying the species Posidonia oceanica. It aims to assess the spatial distribution and health of seagrass meadows using satellite imagery and fieldwork data, along with evaluating the impacts of environmental changes over a 10-year period. The research will employ various remote sensing and GIS methods to achieve accurate mappings for coastal management and conservation efforts.Simon Barchard, RESON

Multi-beam echo sounders can be used for more than just bathymetry. They can be used for bottom classification, leak detection, harbor protection, and detecting sunken heavy oil. A test was conducted at the Ohmsett test facility to detect different types of sunken oil using multi-beam echo sounder data and acoustic backscatter properties. The results showed a 91% detection rate of oil areas with a 20% false alarm rate on non-oil areas.Bruce Carlisle Massachusetts Ocean Management: Implementation Progress and Re...

The document summarizes Massachusetts' progress in implementing its Ocean Management Plan. Key points include:
- The plan established siting standards and identified/mapped special marine habitats and areas of high existing ocean use to guide protection and development.
- Agencies are coordinating regulatory decisions and prioritizing science like improved mapping of habitats and recreational boating data.
- A case study showed how standards guided a cable project to avoid sensitive habitats through routing changes and construction methods.
- An Ecological Valuation Index was developed to systematically evaluate habitat importance, though it has limitations due to data availability.Pcra lecture (camotes pcra orientation)

The document outlines a lecture on coastal resource assessment and management in the Philippines. It discusses the importance of coastal resources, participatory coastal resource assessment (PCRA), and different monitoring methods used in PCRA like manta tow surveys, transect surveys, and fish visual censuses. These methods are used to collect data on coastal habitats, fisheries, and socioeconomic factors to identify issues and inform management guidelines. The lecture aims to familiarize participants with PCRA and apply participatory methods in an actual coastal assessment.Southeastern US Marine Ecosystems and Hydrocarbon Exploration

This document discusses marine ecosystems and hydrocarbon exploration in the southeastern United States. It notes the high biodiversity in estuaries and coastal waters, as well as the influence of the Gulf Stream on regional oceanography. While nearshore areas are relatively well-studied, knowledge declines rapidly with increasing distance offshore and depth. Important issues include degraded habitat and overfishing. Further research is needed on deep-sea and mesopelagic environments over 200 meters deep to better understand biology, habitats, and connectivity in these poorly known areas.Application of remote sensing in coastal zone management

This document discusses the application of remote sensing in coastal zone management. It begins with an introduction to coastal zones and their importance. It then discusses remote sensing concepts like the electromagnetic spectrum and geographical information systems (GIS). The main applications of remote sensing discussed are the study of coastal habitats like coral reefs and mangroves, shoreline protection, monitoring marine water quality, understanding marine environment and climate change impacts, and aiding coastal zone management. Specific examples are provided of how remote sensing has been used to map and monitor these coastal features and issues in India.Final Manuscript ACCURATE COLD SEEP IDENTIFICATION etc_Rev AJD_25-2-2016

The document describes a new multi-beam survey methodology used to map cold seeps and structured benthic communities in the Gran Fuerte area of the Colombian Caribbean. Key findings:
1) The methodology involved double coverage of the survey area to eliminate backscatter artifacts and more accurately map seep boundaries and categorize seeps.
2) Over 200 cold seeps ranging in size were identified, with 93% of predicted seeps confirmed by sediment cores.
3) Seeps could be categorized as "dense", "low density", or "traces" based on backscatter patterns, indicating activity levels.
4) Drift camera surveys confirmed communities identified by the new methodology. No hard substratesMappingMangroves

This document summarizes a study that aimed to map mangrove species in the Seychelles using remote sensing techniques. The study area was Port Launay wetland on Mahe island, which contains seven mangrove species. Field data was collected using GPS to record species locations and analyze spatial patterns. A Pleiades satellite image was analyzed to classify and map the mangrove species distributions. Issues encountered included tidal access limitations and canopy cover obscuring understory species. The analysis will produce a final mangrove species classification map and provide methodology for future remote sensing wetland studies.Diversitas Danis

This document discusses the SCAR-MarBIN (Marine Biodiversity Information Network) project which aims to quantify Antarctic marine biodiversity. It notes that Antarctic biodiversity is highly endemic but understudied, especially in deep-sea environments. SCAR-MarBIN builds an open-access network of over 60 editors to aggregate data on over 16,000 Antarctic taxa and 9,234 species from 130 datasets. The project helps identify gaps in knowledge, promotes new initiatives to increase data, and builds bridges across disciplines and nations to advance conservation and management of Antarctic ecosystems.Predicting suitable habitat for the european lobster, by Ibon Galparsoro, EUR...
