Carbon and nitrogen accumulation in the economic seaweed Gracilaria lemaneiformis affected by ocean acidification and increasing temperature

International Atomic Energy Agency (IAEA) Publications

During mariculture period, maricultured macroalga Gracilaria lemaneiformis experienced seasonal temperature changes. In this study, we examine the effects of predicted ocean acidification...

Impacts of elevated CO2 on organic carbon dynamics in nutrient depleted Okhotsk Sea surface waters

International Atomic Energy Agency (IAEA) Publications

Increasing CO2 in seawater (i.e. ocean acidification) may have various and potentially adverse effects on phytoplankton dynamics and hence the organic carbon dynamics. We conducted a CO2...

Effect of seawater carbonate concentration on foraminiferal carbon and oxygen isotopes

International Atomic Energy Agency (IAEA) Publications

Stable oxygen and carbon isotope measurements on biogenic calcite and aragonite have become standard tools for reconstructing past oceanographic and climatic change. In aquatic organisms,...

Publications

Ocean warming and acidification have complex interactive effects on the dynamics of a marine fungal disease

International Atomic Energy Agency (IAEA) Publications

Diseases threaten the structure and function of marine ecosystems and are contributing to the global decline of coral reefs. We currently lack an understanding of how climate change...

The combined effects of ocean acidification, mixing, and respiration on pH and carbonate saturation in an urbanized estuary

International Atomic Energy Agency (IAEA) Publications

Puget Sound is a large estuary complex in the U.S. Pacific Northwest that is home to a diverse and economically important ecosystem threatened by anthropogenic impacts associated with...

Publications

Synergistic effects of climate-related variables suggest future physiological impairment in a top oceanic predator

International Atomic Energy Agency (IAEA) Publications

By the end of this century, anthropogenic carbon dioxide (CO2) emissions are expected to decrease the surface ocean pH by as much as 0.3 unit. At the same time, the ocean is expected to...

An in-situ sensor technology for simultaneous spectrophotometric measurements of seawater total dissolved inorganic carbon and pH

International Atomic Energy Agency (IAEA) Publications

A new, in-situ sensing system, Channelized Optical System (CHANOS), was recently developed to make high-resolution, simultaneous measurements of total dissolved inorganic carbon (DIC) and...

Elevated CO2 does not exacerbate nutritional stress in larvae of a Pacific flatfish

International Atomic Energy Agency (IAEA) Publications

Multiple aspects of climate change are expected to co-occur such that ocean acidification will take place in conjunction with warming and a range of trophic changes. Previous studies have...

Publications

Tropical CO2 seeps reveal the impact of ocean acidification on coral reef invertebrate recruitment

International Atomic Energy Agency (IAEA) Publications

Rising atmospheric CO2 concentrations are causing ocean acidification by reducing seawater pH and carbonate saturation levels. Laboratory studies have demonstrated that many larval and...

Galápagos coral reef persistence after ENSO warming across an acidification gradient

International Atomic Energy Agency (IAEA) Publications

Anthropogenic CO2 is causing warming and ocean acidification. Coral reefs are being severely impacted, yet confusion lingers regarding how reefs will respond to these stressors over this...

Carbon cycling hysteresis in permeable carbonate sands over a diel cycle: implications for ocean acidification

International Atomic Energy Agency (IAEA) Publications

Dissolved inorganic carbon, dissolved oxygen, H+, and alkalinity fluxes from permeable carbonate sediments at Heron Island (Great Barrier Reef) were measured over one diel cycle using...

Publications

Greenhouse conditions induce mineralogical changes and dolomite accumulation in coralline algae on tropical reefs

International Atomic Energy Agency (IAEA) Publications

Human-induced ocean acidification and warming alter seawater carbonate chemistry reducing the calcification of reef-building crustose coralline algae (CCA), which has implications for...

Publications

Coral calcifying fluid pH dictates response to ocean acidification

International Atomic Energy Agency (IAEA) Publications

Ocean acidification driven by rising levels of CO2 impairs calcification, threatening coral reef growth. Predicting how corals respond to CO2 requires a better understanding of how...

The sounds of silence: regime shifts impoverish marine soundscapes

International Atomic Energy Agency (IAEA) Publications

Context Regime shifts are well known for driving penetrating ecological change, yet we do not recognise the consequences of these shifts much beyond species diversity and productivity....

Ocean acidification and kelp development: Reduced pH has no negative effects on meiospore germination and gametophyte development of Macrocystis pyrifera and Undaria pinnatifida

International Atomic Energy Agency (IAEA) Publications

The absorption of anthropogenic CO2 by the oceans is causing a reduction in the pH of the surface waters termed ocean acidification (OA). This could have substantial effects on marine...
