Despite the rapid increase in number and applications of plankton imaging systems marine science, processing large numbers images remains a major challenge due to variations image content quality different environments. We constructed an automatic recognition enumeration system using enhanced Convolutional Neural Network (CNN) examined performance network structures on classification. The procedure started with adaptive thresholding approach extract Region Interest (ROIs) from situ images,...
[1] Alongshore transport was estimated from the gridded AVISO altimeter data and water level NOAA tide gauges (1993–2010) for northern California Current (NCC) system. The biomass of cold neritic copepods including Calanus marshallae, Pseudocalanus mimus Acartia longiremis (dominants in eastern Bering Sea, coastal Gulf Alaska, NCC) a 15 year time series zooplankton samples (1996–2010) collected biweekly at station 9 km off Newport Oregon U.S.A. alongshore currents exhibit strong seasonal...
Plankton imaging systems are capable of providing fine-scale observations that enhance our understanding key physical and biological processes. However, processing the large volumes data collected by remains a major obstacle for their employment, existing approaches designed either images acquired under laboratory controlled conditions or within clear waters. In present study, we developed semi-automated approach to analyze plankton taxa from ZOOplankton VISualization (ZOOVIS) system turbid...
The 2011 oil spill in the Bohai Sea was largest event China. Nine sediment cores were taken near site and environmental factors including Polycyclic Aromatic Hydrocarbon (PAHs), oils, sulfides, organic carbon measured 6 months later. Benthic foraminifera separated into >150 μm (large) 63-150 (small) size fractions for 2-cm depth interval of each core. Statistical analyses suggested that species composition living impacted by PAHs sulfides. Large more sensitive to oils than small. Abnormal...
A high-resolution digital imaging system, the zooplankton visualization and system (ZOOVIS) was deployed in mid-region of Chesapeake Bay to investigate fine-scale distribution small individuals lobate ctenophore Mnemiopsis leidyi. Counts individuals, mostly <5 mm, were enumerated from each frame ZOOVIS merged with data a conductivity-temperature-depth provide corresponding values depth, temperature salinity. leidyi rarely occurred below pycnocline depth but commonly upper water column. Where...
The frequency and intensity of harmful algal blooms (HABs) are likely to increase with climate change increases in nutrients due anthropogenic activities. To manage the environment health threats surrounding organisms, it is essential improve our capability provide early warning species. Using Noctiluca scintillans as example, a dinoflagellate that often Asia whose presence rapidly expanding worldwide, we demonstrate potential way predict N. by deploying an in-situ plankton imaging system:...
Plankton are excellent indicators of ecosystem status and fisheries because their pivotal role in marine food webs core values the integrated assessment (IEA). Monitoring plankton is essential to understand dynamics underlying processes. Recent advances imaging technologies have enabled situ, high-frequency, real-time observations coastal waters. While high-frequency time series provided unprecedented fundamental information about physical biological processes, understanding identifying...

Human impact on the environment remains at center of debate global environmental change. Using Hong Kong-Shenzhen corridor in south China as an example, we present evidence that rapid urbanization and economic development coastal areas were dominant factors causing changes waters. From 1990 to 2012, seawater temperature increased ~ 0.060 °C per year, sea level rose 4.4 mm year pH decreased from 8.2 7.7, much faster than averages. In same period, there exponential increases local population,...
The abundance of the subarctic copepod, Calanus finmarchicus, and temperate, shelf Centropages typicus, was estimated from samples collected bi-monthly over Northeast U.S. continental (NEUS) 1977-2010. Latitudinal variation in long term trends seasonal patterns for two copepod species were examined four sub-regions: Gulf Maine (GOM), Georges Bank (GB), Southern New England (SNE), Mid-Atlantic Bight (MAB). Results suggested that there significant difference between northern region (GOM GB),...
Abstract We determined the habitat usage and connectivity of juvenile Chinook ( Oncorhynchus tshawytscha ) coho kisutch salmon in continental shelf waters off Washington Oregon, based on samples collected every June for 9 yr (1998–2006). Habitat were evaluated using SeaWiFS satellite‐derived chlorophyll a data water depth. Logistic regression models developed both species, habitats first classified threshold value estimated from receiver operating characteristic curve. A Bernoulli random...
Abstract. The N/P ratio of nutrient uptake, the change dissolved inorganic nitrogen (DIN) relative to phosphorus (DIP), is a key parameter for many ecological models. In Baltic Sea ecosystem, uptake varies among different basins and seasons. alteration, i.e., DIN DIP altered before after spring blooms, not same as but former can be regarded an indicator latter in Sea. Based on observed we hypothesize non-Redfield uptake. 3-D-ecosystem model ERGOM coupled with circulation DMI-BSHcmod was used...
