Abstract: Two major deep learning methods for semantic segmentation, i.e., patch-based convolutional neural network (CNN) approaches and fully convolutional neural network (FCNN) models, are studied in the context of classification of regions in underwater images of coral reef ecosystems into biologically meaningful categories. On 32 of these reefs density estimates were made using two different survey methods. METHODS FOR CORAL REEF SURVEYS OSCAR BEIJBOM, UCSD DESSC meeting San Francisco, Dec 8 2013 . Benthic Cover Field Method Upon completion of the fish survey, one diver conducted a photoquadrat by photographing the benthos at 1-m intervals along the 30-m transect line between the centers of the two cylinders (30 photographs per site). We assess the diversity, abundance and size structure of stony corals, the number of young coral individuals, and coral health. African elephants provide a powerful case study for how science can inform conservation. In order to prevent bias, some tips to help randomize your selection may include pre-determining your bearings, establishing distance between coral selection, or closing your eyes and swimming a certain number of finkicks before opening your eyes and selecting the first coral you observe. For example manta towing can provide a broad scale survey of reefs for assessment of threats such as crown-of-thorns, coral bleaching, coral disease, anchor damage, destructive fishing. Here, we test this assumption by comparing the denticle record in surface sediments to three conventional shark survey methods at Palmyra Atoll, Line Islands, central Pacific Ocean, where shark density is high and spatially heterogeneous. Reef species diversity has been estimated at ∼600,000 to more than 9 million species worldwide – This diversity is concentrated in the central Indo-Pacific (the “Coral Triangle”), and decreases with increasing distance from the Indo-Australian archipelago. An international group of scientists has surveyed more than 2,500 coral reef systems across 44 countries to determine how to save them in the … These methods were developed for research with the Hawaii Coral Reef Initiative Program and are being compiled for a Methods Manual to be distributed by HCRI. solaris were completed on fourteen reefs in the Cairns sector of the Great Barrier Reef (GBR) (Fig 1).. The Coral Health Chart records changes in coral colour and is a simple tool for people to monitor coral colour as an indicator of coral health. The manual was written by Linda Preskitt and edited by Celia M. Smith and I.A. For example manta towing can provide a broad scale survey of reefs for assessment of threats such as crown-of-thorns, coral bleaching, coral disease, anchor damage, destructive fishing. The coral survey consists of recording the size, species, and health of every coral along a transect, allowing for an accurate assessment of the coral community on each reef.

An investigation of optimum methods and unit sizes for the visual estimation of abundances of some coral reef organisms. Ideally a coral reef manager will perform a detailed baseline survey that includes many measures or parameters that may or may not change over time. Middleton and Elizabeth Reefs are platform reefs associated with a seamount chain that extends northward from Lord Howe Island, managed by the Australian Government as part of the Lord Howe Marine Park. Coral reef fish come in a variety of shapes and colors. 1| Reef Life Survey Assessment of Coral Reef Biodiversity in the Coral Sea 1 Introduction This report and the surveys on which it is based were undertaken to greatly increase information on the distribution of marine biodiversity across the Coral Sea CMR, with major objectives: (i) to The survey methods are based on these previous volunteer projects and the globally recognized Reef Check (www.reefcheck.org) and Coral Watch (www.coralwatch.org) methods. dATA cOLLECTION. Databases described in the paper can be accessed here . Coral recruits are defined operationally for this assessment as any stony coral that is greater than 1.0 cm² and less than 4.0 cm². We assembled case studies and descriptions of coral restoration methods from four sources: 1) the primary literature (i.e. Daniela M. Ceccarelli, Graham Edgar, Antonia Cooper, Andrew S. Hoey, Morgan S. Pratchett & Rick D. Stuart-Smith. This approach assumes that denticle accumulation rates correlate with shark abundances. Your objective may be quite general, such as "to determine the present status of the reef and natural rates of change," or it may be more specific, such as, Ø to detect changes in abundances of a particular group of organisms; It is the most comprehensive record of reef condition available for the Reef. Monitoring and Assessment Methods. These methods are applied by all RLS divers no matter where in the world they undertake a survey, and thus allow for direct comparisons to be made between any sites surveyed by RLS. Students calculate their data and make estimates of fish populations for a designated area of the classroom. CORAL COMMUNITY STRUCTURE. Specific methods are used at study sites depending on the resource management concerns that DAR is looking to address, and include surveys of abundance of resource and herbivorous fish, smaller cryptic fish and recruits, urchins and larger mobile invertebrates, benthic habitat cover, coral health and biological diversity. Listed below are links or Network postings on most of the major sampling protocols used by various research programs throughout the world. Due to frequent bleaching events that coral reefs are facing, there has been an increase in the activity of researchers to understand and mitigate the effects of various stressors and to conserve the corals and coral reefs into the future. Our initiative is built on over 20 years of global reef … This interactive module explores methods used to survey large animal populations, and what they have revealed about the current state of the African elephant population. RLS applies globally standardised underwater visual census (UVC) methods developed over 30 years of shallow reef biodiversity research. The strategy was to survey coral sites reported in the literature and by the fishermen.
