Design Optimization of Surface Seawater Intake Piping for Hybrid Ocean Thermal Energy Conversion Pilot Plant

Energy Science &Engineering, EarlyView.
ABSTRACT Hybrid Ocean Thermal Energy Conversion (H‐OTEC) systems are characterized by the adoption of both open‐loop and closed‐loop Rankine cycles. In the closed‐loop configuration, a working fluid such as ammonia is evaporated in a heat exchanger, utilizing the heat from water vapor generated in a vacuum chamber by warm surface seawater introduction.

Increase in CH4 Emissions in a Pantanal Wetland Lagoon Due to Extreme Drought and Sediment Exposure

International Review of Hydrobiology, EarlyView.
ABSTRACT The Pantanal, one of the largest wetlands on Earth, stores substantial carbon in its diverse ecosystems but faces increasing threats, such as fires, poor soil management, deforestation, and climate change impacts that may elevate CH₄ emissions.

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

International Review of Hydrobiology, EarlyView.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

Waiting for the rains: An attempt to evaluate the efficiency of the large Roman cistern at Barbariga Stancija (Casematte, Istria, Croatia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Access to freshwater has always been a critical factor in sustaining human settlements, especially in regions with limited water resources. In the Mediterranean region, where dry summers and karst landscapes limit water availability, ancient societies developed advanced methods for collecting and storing rainwater. Among these, cisterns played

Intensification of the Southern Hemisphere westerly winds during the last deglaciation (18.5–14.0 cal ka BP): Evidence from Pearly Beach wetland on the southern Cape coast of South Africa

Journal of Quaternary Science, EarlyView.
ABSTRACT The southwestern Cape of South Africa experiences a complex and dynamic climate, shaped by the interplay between the temperate Southern Hemisphere westerly winds and the subtropical easterlies. Despite the climatic sensitivity of the region, relatively few studies have examined how conditions have varied since the last deglaciation in response

Nutrient enrichment—but not warming—increases nitrous oxide emissions from shallow lake mesocosms

Limnology and Oceanography, EarlyView.
Abstract Shallow lakes and ponds play a crucial role in the processing of carbon and other nutrients. However, many lakes and ponds worldwide are affected by climate change and nutrient pollution. How these pressures affect the emission of the greenhouse gas nitrous oxide (N2O) is unclear.

A perspective on the future of physical oceanography

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
The ocean flows because it is forced by winds, tides and exchanges of heat and freshwater with the overlying atmosphere and cryosphere. To achieve a state where the defining properties of the ocean (such as its energy and momentum) do not continuously ...

Plankton communities today and tomorrow—potential impacts of multiple global change drivers and marine heatwaves

Limnology and Oceanography, EarlyView.
Abstract In the context of global change, marine organisms are subjected not only to gradual changes in abiotic parameters, but also to an increasing number of extreme events, such as heatwaves. However, we still know little about the influence of heatwaves on the structure of marine communities, and experimental studies are needed to test the impact ...

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

Limnology and Oceanography, EarlyView.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Blooms of filamentous cyanobacteria reduce zooplankton quality and pelagic food web efficiency

Limnology and Oceanography, EarlyView.
Abstract Cyanobacterial blooms in marine and freshwater ecosystems have increased in magnitude, frequency, and distribution worldwide during recent decades. Filamentous cyanobacteria are of unsuitable size for mesozooplankton feeding and of poorer nutritional quality than other phytoplankton taxa. The production and quality of higher trophic levels are
