editorial for the special issue remote sensing in coastal zone monitoring and management how can remote sensing challenge the broad spectrum of temporal and spatial scales in coastal zone dynamic
Remote Sensing, 2019Co-Authors: David Doxaran, Javier Bustamante, Ana I Dogliotti, T J Malthus, Nadia SenechalAbstract:Coastal zones are sensitive areas responding at various scales (events to long-term trends) where the monitoring and management of physico-chemical, biological, morphological processes, and fluxes are highly challenging. They are directly affected by anthropization (urbanization, industrialization, agri-and aquaculture) and climate change (e.g., river discharges, waves, sea-level rise). Coastal waters only represent 15% of the global ocean, but concentrate 90% of commercial fisheries, contribute to 25% of global biological productivity, and represent 80% of the marine biodiversity, while being associated with an intensive tourism-related economy. The monitoring and management of coastal zones require past, present, and future observations adapted to quite diverse and dynamic environments. To complement field measurements, the use of remote sensing data provides useful information to map the hydromorphological (freshwater discharge, currents, shoreline evolution), physico-chemical (water transparency, temperature, salinity, oxygen, nutrients, and pollutants), and biological (habitats, phytoplankton blooms) properties of the coastal zones. This special issue highlights how the monitoring of coastal zones benefits from both long-term (~40 years) and recent capabilities of remote sensing observations. It also provides new methodologies to optimize the combined use of multi-mission satellite/airborne data and field measurements for an integrated approach. Considering different types of coastal environments (bays, estuaries, sandy and muddy systems), several key land and water quality (vegetation, temperature, concentrations of suspended particulate matter and polychlorinated biphenyl, aquatic plants) and morphological (shorelines, Mudbanks, wetlands) parameters can be remotely sensed at various spatial and temporal scales, using innovative methods and providing validated products.

some observations on the beakedsea snake enhydrina schistosa daudin 1803 in the Mudbank area off alapuzha kerala southwestcoast of india
2015Co-Authors: R Jeyabaskaran, K S Abhilash, Abbas A Mohammed, Gishnu Mohan, P G Vishnu, L R Khambadkar, K S Aswathy, D PremaAbstract:Hook-nosed sea snake or beaked snake, Enhydrina schistosa were caught during experimental fishing operations in the Mudbank region along central Kerala Coast at depths ranging from 6 to 12 m. The sea snakes were found to form aggregations of 5 to 6 numbers and were able to tolerate highly turbid waters. The catfish Arius jella and the puffer fish Lagocephalus inermis were the dominant prey items. Mudbanks are unusually calm areas which form along the Kerala coast during the monsoon. The inshore waters including the Mudbanks are intense fishing areas of non mechanized crafts during the monsoon. The presence of venomous sea snakes is precarious and there is a need to give awareness programme for the fishers about this danger.

Aggregation of beaked sea snake Enhydrina schistosa (Daudin, 1803) in Mudbank area of southwest coast of India
2014Co-Authors: R Jeyabaskaran, K S Abhilash, Abbas A Mohammed, Gishnu Mohan, P G Vishnu, L R Khambadkar, KripaAbstract:The beaked sea snake Enhydrina schistosa (Daudin, 1803) is commonly found all along the Indian coast. There are about 22 species of sea snakes belonging to 3 families and 3 sub-families reported from Indian waters. All the sea snakes in India are protected under India Wildlife Protection Act 1972. During a special cruise by onboard FRV Silver Pompano for Mudbank research, a shrimp trawl was operated in the near shore at 6 meter depth and offshore at 12 meter depth along Alappuzha coast. The beaked sea snakes were caught during each haul and immediately released into the sea in live condition. About 2 to 5 specimens regularly occurred in the catch at 12 meter depth in each haul and the number was always higher at 6 meter depth. The length of the specimens caught ranged between 51.7 and 112.6 cm. On 5th June, 2014 about 20 numbers of beaked sea snake were caught from the same location. The sea bottom was muddy and it was observed that the beaked sea snakes preferred to live in shallow muddy areas. The stranding of 4 to 6 dead beaked sea snakes were observed almost every day at Punnapara coast of Alappuzha, where the Mudbank is formed during monsoon. The food and feeding habits of beaked sea snakes also studied based on the stomach content analysis. The snakes caught in the 6 meter depth, cat fish was the dominant food item and snakes caught at 12 meter depth pufferfish were predominant. The cat fish was identified as Arius jella and the puffer fish was Lagocephalus inermisis. Occurrence of the school of Arius jella occurrence was common in Mudbank area; hence the beaked sea snake abundance was more. The feeding behaviour of beaked sea snakes also noticed. It was observed that they always ingest head portion of the prey (fish) first. The morphological features and biology of the beaked sea snake are discussed in the paper in detail.
