Estimating the total mortality of seabirds following a marine heat wave

Conservation Biology, EarlyView.
Abstract Marine heat waves detrimentally affect a range of marine species, including seabirds, and are increasing in frequency and severity. When thousands of dead seabirds wash up on beaches, the public becomes concerned. However, the number of dead birds recorded on beaches is only a fraction of the total mortality; most birds perish at sea.

The Effects of Nutrient Additions on Kokanee in Dworshak Reservoir, Idaho

Fisheries Management and Ecology, EarlyView.
ABSTRACT We investigated the effects of whole reservoir nitrogen (N) addition on kokanee growth in Dworshak Reservoir, Idaho. We hypothesized that N addition would improve the growth of kokanee (Oncorhynchus nerka) at a given level of abundance by increasing the availability of Daphnia, an important food source.

Effects of Dissolved Oxygen and Hypoxia on Catch Rates of Nearshore Groundfishes in a Recreational Hook and Line Fishery

Fisheries Oceanography, EarlyView.
ABSTRACT Global climate change is intensifying ocean deoxygenation, particularly in eastern boundary current systems such as the California Current. This study investigates the impact of hypoxic events on a nearshore, multispecies recreational groundfish fishery along the Oregon coast.

Utilizing Downwelling Irradiance for Phytoplankton Determination [PDF]

, 2012
The downwelling irradiance is rarely utilized to determine optical parameters of a water body since the ever-changing water surface induces strong signal fluctuations in the upper meters of typically 20 to 40 %.

A Fishery‐Dependent CPUE‐Based Proxy Index for Juvenile Japanese Anchovy (Engraulis japonicus) Recruitment Variability in Southeastern Korea: Associations With Lagged Climate‐Ocean Conditions

Fisheries Oceanography, EarlyView.
ABSTRACT We developed and evaluated a fishery‐dependent catch‐per‐unit‐effort (CPUE)‐based proxy index for juvenile Japanese anchovy (Engraulis japonicus) recruitment‐related variability in the southeastern coastal waters of Korea. The proxy was constructed from bimonthly CPUE of the smallest juvenile size class (20–40 mm) in the anchovy drag‐net ...

An Investigation into changes in the phytoplankton community in Loch Creran, a Scottish sea loch [PDF]

Short term and irregular sampling in Loch Creran over recent decades suggested that changes may be occurring in the phytoplankton community in the loch. This study sought to confirm this suggestion. After instigating a regular sampling regime during 2008

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Biogeochemical Markers to Identify Spatiotemporal Gradients of Phytoplankton across Estuaries

Coasts
The spatiotemporal distribution of phytoplankton in estuaries is indicative of processes and transport across the land–ocean aquatic continuum (LOAC). Estuaries, as biogeochemically and physically active systems, process large amounts of nutrients and ...
