The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, EarlyView.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

Upwelling intensity structures free-living and particle-associated bacterial communities in an eastern boundary upwelling system

Frontiers in Marine Science
Eastern Boundary Upwelling Systems (EBUS) are among the most productive oceanic regions, driven by the upwelling of cold, nutrient-rich, and low-oxygen waters. These systems are increasingly affected by climate change, with intensified upwelling activity

Modelling upwelling

, 2020
Upwelling is a process in which cold water, rich in nutrients and small fish, rises towards the surface. Some countries of the Global South have based their economy on this godsend, for better or for worse… As these areas are temperamental and sensitive to climate variability.

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.

Struktur vertikal upwelling – downwelling di Samudera Hindia Selatan Jawa hingga Selatan Bali berdasarkan salinitas musiman periode 2004 – 2010

Depik Jurnal, 2013
Salinitas berperan penting untuk mengidentifikasi fenomena upwelling dan downwelling. Upwelling yang terjadi di samudera Hindia Selatan Jawa hingga Selatan Bali dipengaruhi oleh angin musim, ENSO (El Nino Southern Oscillation) dan IOD (Indian Oscillation

Influence of coastal upwelling on the air–sea gas exchange of CO2 in a Baltic Sea Basin

Tellus: Series B, Chemical and Physical Meteorology, 2013
During coastal upwelling cold water from the ocean interior with high CO2 concentration is brought up to the surface, allowing this water to interact with the atmosphere. This sets the stage for events with potentially altered sea–air CO2 fluxes.

Solution of a Model for the Oceanic Pycnocline Depth: Scaling of Overturning Strength and Meridional Pressure Difference

, 2004
We present an analysis of the model by Gnanadesikan [1999] for the pycnocline depth in the ocean. An analytic solution for the overturning strength as a function of the meridional pressure difference is derived and used to discuss their mutual scaling ...

Larval Arctic cod (Boreogadus saida) exhibit stronger developmental and physiological responses to temperature than to elevated pCO2

Journal of Fish Biology, EarlyView.
Abstract High‐latitude ecosystems are simultaneously warming and acidifying under ongoing climate change. Arctic cod (Boreogadus saida) are a key species in the Arctic Ocean and have demonstrated sensitivity to ocean warming and acidification as adults and embryos, but their larval sensitivity to the combined stressors is unknown. In a laboratory multi‐

Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, EarlyView.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

The middle Pleistocene extinction of bathyal benthic foraminifera in the South Atlantic (ODP sites 1082 and 1088) : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Science at Massey University [PDF]

, 2005
The youngest major turnover in deep-sea benthic foraminifera (termed the Stilostomella extinction) is documented in two ODP sites in the South Atlantic Ocean.
