No turning back? Ecosystems over time have endured much disturbance, yet they tend to remain intact, a characteristic we call resilience. Though many systems been lost and destroyed, for that physically there is debate as whether changing temperatures will result in shifts or collapses. Wernburg et al. show extreme warming of temperate kelp forest off Australia resulted not only its collapse, but also shift community composition brought about an increase herbivorous tropical fishes prevent...
In subtropical ocean gyres, anticyclonic eddies increase surface nutrient injection and primary production during winter.
Gridded SST products developed particularly for offshore regions are increasingly being applied close to the coast biogeographical applications. The purpose of this paper is demonstrate dangers doing so through a comparison reprocessed MODIS Terra and Pathfinder v5.2 SSTs, both at 4 km resolution, with instrumental in situ temperatures taken within 400 m from coast. We report large biases up +6°C places between satellite-derived climatological 87 sites spanning entire ca. 2 700 South African...
A unique feature of the subtropical South Indian Ocean is existence anticyclonic eddies that have higher chlorophyll concentrations than cyclonic eddies.Off Western Australia, this anomalous behavior related to seeding with shelf water enriched in phytoplankton biomass and nutrients.Further off-shore, two mechanisms been suggested explain eddy/chlorophyll relationship: (i) originating from Australian coast maintain their anomaly while propagating westward; (ii) eddy-induced Ekman upwelling...
Despite increasing awareness of large-scale climate-driven distribution shifts in the marine environment, no study has linked rapid ocean warming to a shift and consequent hybridization fish species. This describes (0.8 °C per decade) coastal waters Angola-Benguela Frontal Zone over last three decades concomitant by temperature sensitive species (Argyrosomus coronus) southward from Angola into Namibia. In this context, across Economic Exclusive Zones will complicate management fishes,...
Coastal ecosystems are highly vulnerable to human-mediated drivers of global change because they located at the land–ocean interface and often host centres urbanisation development. The South African coastline comprises several distinct coastal ecoregions that support a wide range (inshore) ecosystems, including rocky, sandy mixed shores, kelp beds, estuaries seagrass communities. A growing body evidence indicates local air sea temperatures, wind patterns, ocean current speed upwelling...
Abstract The transformation of internal waves on continental shelves is important to mass transfer, nutrient replenishment, and heat transfer. Yet, the transfer energy from larger smaller scale or between nonlinear (NLIW) themselves remains poorly understood. We present 1 month through water column observations temperature currents southeast shelf Bay Biscay, a region where wave dynamics have never been described. Over shallower part shelf, relatively strong baroclinic dynamic exists, with...
Abstract The South Indian Ocean subtropical gyre has been described as a unique environment where anticyclonic ocean eddies highlight enhanced surface chlorophyll in winter. processes responsible for this increase anticyclones have remained elusive, primarily because previous studies investigating unusual behavior were mostly based on satellite data, which only views the surface. Here we present situ data from an oceanographic voyage focusing mesoscale variability of biogeochemical variables...
A regional ocean model was used to study interannual variations in the Tanzanian shelf region and offshore tropical western Indian Ocean for period 1980–2007. The forced with surface winds heat fluxes from National Centers Environmental Prediction (NCEP) reanalysis, its initial lateral boundary conditions were derived Simple Data Assimilation (SODA). weakest sea temperature (SST) occurred coastal waters off Tanzania, where there a strong correlation north of Madagascar. dominated by...
Abstract The Australian marine research, industry, and stakeholder community has recently undertaken an extensive collaborative process to identify the highest national priorities for wind-waves research. This was under auspices of Forum Operational Oceanography Surface Waves Working Group. main steps in were first, soliciting possible research questions from via online survey; second, reviewing at a face-to-face workshop; third, ranking by individuals. resulted 15 identified priorities,...
Abstract Owing to their strong forcing at the air‐sea interface, tropical cyclones are a major driver of hydrodynamics and sediment dynamics continental shelves, strongly impacting marine habitats offshore industries. Despite North West Shelf Australia being one most frequently impacted cyclone regions worldwide, there is limited knowledge how influence this shelf region, including significance these episodic extreme events normal background conditions that occur. Using an extensive 2 year...
The present contribution aims to provide an insight into the sediment dynamics of Bay Marseille (BoM), France, area characterised by a mostly rocky, steep-sloped, and protected shoreline. In terms composition, northern part study is dominated fines, whereas sands mean grain size 0.2 < d50 1 mm occur at most other locations. Posidonia oceanica meadows occupy many nearshore areas. Critical bed-shear stress was determined through tests in unidirectional flume using 15 natural cores. Measured...
