In this paper, we present results of predicting algal blooms in one estuary in South East Tasmania, Australia. Further we also present results of a detection method for harmful algal blooms in another estuary in the same region. The research on detecting and predicting algal blooms is towards building ...
The increase in frequencies and the noxious effects of HABs in global coastal waters have led to enhanced interest in monitoring and detecting of such blooms. In December 2009, a toxic bloom hit Singapore waters along East Johor Strait causing massive fish kills and great economic losses. Interdisciplinary ...
Multi-nested operational prediction system for the Yellow Sea (YS) has been developed to predict the movement of oil spill. Drifter trajectory simulations were performed to predict the path of the oil spill during the Hebei Spirit accident. The oil spill trajectories at the surface predicted by model ...
The Bulgarian National Operational Marine Observing System (NOMOS) is a system of systems designed to allow the real-time assessment of weather and marine conditions in the coastal, shelf and open sea areas of the western part of Black Sea. NOMOS consists of several subsystems: POMOS, Galata, Shkorpilovtci, ...
Both waves and currents rank highly by user groups among oceanographic observation variables. Real-time information of these variables is especially useful for vessel operators and recreational users in and around ports, harbors and bays. Other applications include coastal land management, ecosystem ...
The characterization of biomass and its dynamics provides valuable information for the assessment of natural and transplanted eelgrass populations. The need for simple, nondestructive assessments has led to the use of the leaf biomass-to-length ratio for converting leaf-length measurements, which can ...
Hemagglutinating proteins (HAPs) were purified from Poker-chip Venus (Meretrix lusoria) and Corbicula clam (Corbicula fluminea) using gel-filtration chromatography on a Sephacryl S-300 column. The molecular weights of the HAPs obtained from Poker-chip Venus and Corbicula clam were 358 kDa and 380 kDa, ...
Resistance and tolerance are two complementary mechanisms to reduce the detrimental effects of parasites, pathogens, and production diseases on host performance. Using body weight and ascites data on domesticated chicken Gallus gallus domesticus, we demonstrate the use of random regression animal model ...
A Water Quality Index (WQI) is a useful statistical tool for simplifying, reporting and interpreting complex information obtained from any body of water. A simple number given by any WQI model explains the level of water contamination. The objective was to develop a WQI for the water of the Luis L. ...
The avermectins, milbemycins and spinosyns are collectively referred to as macrocyclic lactones (MLs) which comprise several classes of chemicals derived from cultures of soil micro-organisms. These compounds are extensively and increasingly used in veterinary medicine and agriculture. Due to their ...
In recent years, in developed countries and around the world, lifestyle-related diseases have become a serious problem. Numerous epidemiological studies and clinical trials have demonstrated that diet is one of the major factors that influence susceptibility to lifestyle-related diseases, especially ...
Fish species are diverse. For example, some exhibit early maturation while others delay maturation, some adopt semelparous reproductive strategies while others are iteroparous, and some are long-lived and others short-lived. The diversity is likely to have profound effects on fish population dynamics, ...
Pinger tags have long been used as a method of tracking fish movements. Typically, tags are either fixed to fish manually using catch and release methods, or the fish are allowed to ingest the tags through the use of baited lines. In the study of tuna species, long lines fitted with pinger tags and ...
The evaluation of the behaviors of fish which stand on higher trophic level is important from the viewpoint of the resource management or other environmental impacts. Especially for the adult fish which can swim against the currents of circumference, considering the migration effects in the model is ...
In this paper, we present an inexpensive system for diverless video capture and fast image stitching of image frames for rapid reef assessment of shallow coral reefs. Our system has two main components: 1) Teardrop, a boat-towable, winged hull apparatus designed to house a commercial digital camera, ...
The United States Integrated Ocean Observing System (IOOS®) is a user-driven, coordinated network of people, organizations, and technology that generate and disseminate continuous data about our coastal waters, Great Lakes, and oceans supported by strong research and development activities. IOOS® is ...
This study developed a whole-implicit algorithm and virtual neural lattice to model and simulate the dynamics of pelagic longline gear. The programming, model calculation and behavior simulation of longline dynamics were implemented in R language. Equilibrium state and stable solution of the models ...
The upsurge in piracy and the impact of recent environmental disasters have highlighted the need to improve maritime surveillance. Governmental and private initiatives have developed monitoring systems with improved acquisition and analysis capabilities. These systems rely on one major component, namely ...
The abundance and biological characteristics of twaite shad (Alosa fallax), and the the reasons of its population recovery in Lithuania is presented in this study. Migratory fish are extremely susceptible to changes in environmental conditions. For a long time twaite shad have been enjoying the status ...
Oil spills can harm marine life in the oceans, estuaries and wetlands. To limit the damage by a spill and facilitate cleanup efforts, emergency managers need information on spill location, size and extent, direction and speed of oil movement, and wind, current and wave information for predicting oil ...
