The purpose of the National Oceanic and Atmospheric Administration (NOAA) CoastWatch/OceanWatch/PolarWatch Program (a.k.a. “CoastWatch”, https://coastwatch.noaa.gov) is to improve decision outcomes by facilitating the use of ocean satellite data in applications and research. NOAA CoastWatch provides ...
With the increasing availability of high-resolution comprehensive spatio-temporal ocean models and observation systems, ocean data visualization has become ubiquitous. This is due to the major impact of ocean products on disaster management, shipping, fisheries, autonomy, coastal operations, and scientific ...
Five Unmanned Surface Vehicles (USVs) were deployed off the west coasts of the U.S. and Canada in summer 2018 as a first step toward evaluating the effectiveness and efficacy of USVs as survey/research platforms. The Saildrone USVs (Saildrone, Inc.) surveyed a total of 5,400 nmi along 124 transects ...
Multibeam echosounder (MBES) technology has been constantly evolving since its commercial introduction in the late 1970s. The early systems were large and designed to efficiently acquire bathymetric data in deep water. As the underlying sonar technologies improved and computing power increased, systems ...
In a perfect acoustic world, acoustic backscatter energy would only be received from targeted animals in experimental measurements or surveys. Backscatter from unwanted targets is considered noise. To increase backscatter from targets of interest the amount of energy in the transmit pulse can be increased ...
Over the past few decades coastal regions have experienced considerable socio-economic change. Accompanying these socio-economic shifts are unprecedented environmental changes, which include variation in magnitude and frequency of extreme weather events, marine heatwaves, increased ocean acidification, ...
Over the last 30 years, we have been fortunate to work closely with Dr. John Ehrenberg in the fisheries sonar and acoustic telemetry research fields. With John's passing in the fall of 2018, we felt it was important to honor John's research with this publication. We were involved in multiple research ...
A novel Doppler based speed measurement technique for free-ranging acoustically tagged fish was developed and validated through a field experiment in a marine aquaculture farm. For emulated swimming speeds in the range 25cms-160cms-1, an rms error of 5cms-1 with a standard deviation of 4.7cms-1 was ...
In the first place, buoy monitoring system is developed to solve the problem of easily discarded fishing nets, that is not only polluting the ocean, but also risking the fishery sustainability. However, this system is also preventive, as it can prevent the loss of fishing nets too. The buoy monitoring ...
This paper shows the results obtained from the evaluation of two methods for the optimization of a Hybrid Renewable Energy System (HRES). The first consists of an algorithm developed in MATLAB. The second is a model developed in the HOMER tool. The potential of a renewable resources, the energy demand ...
Trend Assessment and Scenario Development Analysis approach was carried out in this study. This approach is a framework specifically designed to look at the direction of technological development and possible conditions that occur in the future. First stage of the framework consists of the Delphi study, ...
This paper presents a study on the different threats underwater communication cables are exposed. The study goes towards the identification of the sensors that could be used to detect such threats. Sensors of different kind have been studied and reported, such as acoustic, magnetometers, optical and ...
In 2015, the United Nations defined the Sustainable Development Goals (SDG), which include a target (12.3) on food waste. The target requires “by 2030, to halve per capita global food waste at the retail and consumer levels and to reduce food losses along production and supply chains, including post-harvest ...
To cleanup marine plastics, accurate modeling is needed. We outline and illustrate a new partial-differential-equation methodology for characterizing and modeling plastic transports in time and space (4D), showcasing results for Massachusetts Bay. We couple our primitive equation model for ocean dynamics ...
Objective(s): Today, consumers are looking for food products providing health benefits in addition to meeting the basic nutritional needs of the body. This study aimed to evaluate the antioxidant and cytotoxic effects of Liza klunzingeri protein hydrolysate both in vivo and in vitro. Materials and ...
Alzheimer’s disease (AD) is a neurodegenerative disease and the leading cause of dementia worldwide. Epidemiological studies support the important role of diet in prevention and improvement of AD. In Traditional Persian Medicine (TPM), there is multiple dietary guidelines to prevent and alleviate dementia ...
Atypical mycobacterioses are unusual infections of the skin and other organs caused by non-tuberculous mycobacteria. Fish tank granuloma and swimming pool granuloma are two forms of atypical mycobacterioses caused by Mycobacterium marinum. So far, only a few cases of these infections have been reported ...
Introduction It is often presumed that students of health sciences are more vigilant about their diet. This study assessed the prevalence of unhealthy dietary habits and identified its associated factors among students enrolled at a large university for health sciences in the Middle East. Methods A ...
Scombroid poisoning, also known as histamine fish poisoning, typically occurs after eating dark meat fish. Higher levels of histidine, which is converted to histamine, causes anaphylaxis-like symptoms upon ingestion. There are few reported cases of scombroid in humans secondary to light meat fish. We ...
Background and Aim: Anisakis is a global challenge for a fish product which may lead to a decrease in economic value and consumers’ preference. Skipjack (Katsuwonus pelamis) in Kupang, Nusa Tenggara Timur, Indonesia, have important economic value for local fisheries. Anisakis typica is one of the Anisakis ...
