Impact of dust addition on the metabolism of Mediterranean plankton communiti...
Although atmospheric dust fluxes from arid as well as human-impacted areas represent a significant source of nutrients to surface waters of the Mediterranean Sea, studies... -
Ocean Acidification and Organic Matter Enrichment Alter Carbonate Sediment Me...
Ocean acidification (OA) and organic matter enrichment (due to coastal eutrophication) could act in concert to shift coral reef carbonate sediments from a present state of net... -
Seawater carbonate chemistry and abiotic and biotic interactions in the diffu...
Seaweeds are able to modify the chemical environment at their surface, in a micro‐zone called the diffusive boundary layer (DBL), via their metabolic processes controlled by... -
Measurements of microbial processes, dissolution, water and porewater chemist...
Two coral reef sediments have been subjected to OA scenarios in the laboratory. Sediments from Magnetic Island (year 2014, 3 pCO2 treatments) were investigated under diffusive... -
Seawater carbonate chemistry and biological processes during experiments with...
Increasing atmospheric CO2 concentration affects calcification in most planktonic calcifiers. Both reduced or stimulated calcification under high CO2 have been reported in the... -
Seawater chemistry, nutrients, chlorophyll a, and growth rate of Phaeocystis ...
Phaeocystis globosa (Prymnesiophyceae) is an ecologically dominating phytoplankton species in many areas around the world. It plays an important role in both the global sulfur... -
Species-specific consequences of ocean acidification for the calcareous tropi...
Ocean acidification (OA), resulting from increasing dissolved carbon dioxide (CO2) in surface waters, is likely to affect many marine organisms, particularly those that calcify.... -
Interacting effects of CO2 partial pressure and temperature on photosynthesis...
We show here that CO2 partial pressure (pCO2) and temperature significantly interact on coral physiology. The effects of increased pCO2 and temperature on photosynthesis,... -
Seawater carbonate chemistry and biological processes of coral Acropora muric...
The effect of decreasing aragonite saturation state (Omega Arag) of seawater (elevated pCO2) on calcification rates of Acropora muricata was studied using nubbins prepared from... -
Seawater carbonate chemistry and photosynthetic response of Emiliania huxleyi...
Changes in calcification of coccolithophores may affect their photosynthetic responses to both, ultraviolet radiation (UVR, 280-400 nm) and temperature. We operated... -
Combined effects of solar UV radiation and CO2-induced seawater acidification...
We carried out short term pCO2/pH perturbation experiments in the coastal waters of the South China Sea to evaluate the combined effects of seawater acidification (low pH/high... -
Seawater carbonate chemistry and coral community metabolism during year-long ...
We describe year-long experiments in which back reef and fore reef (17-m depth) communities from Moorea, French Polynesia, were incubated outdoors under pCO2 regimes reflecting... -
Seawater carbonate chemistry and growth rate, particulate organic (POC) and i...
Continuous accumulation of fossil CO2 in the atmosphere and increasingly dissolved CO2 in seawater leads to ocean acidification (OA), which is known to affect phytoplankton... -
Seawater carbonate chemistry and phytoplankton stoichiometry, production and ...
There is a growing consensus that the ongoing increase in atmospheric CO2 level will lead to a variety of effects on marine phytoplankton and ecosystems. However, the effects of... -
Physiological responses of coastal and oceanic diatoms to diurnal fluctuation...
Diel and seasonal fluctuations in seawater carbonate chemistry are common in coastal waters, while in the open-ocean carbonate chemistry is much less variable. In both of these... -
Comparative responses of two dominant Antarctic phytoplankton taxa to interac...
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a... -
CO2 and vitamin B12 interactions determine bioactive trace metal requirements...
Phytoplankton growth can be limited by numerous inorganic nutrients and organic growth factors. Using the subarctic diatom Attheya sp. in culture studies, we examined how the... -
Combined effects of CO2 and light on large and small isolates of the unicellu...
We examined the combined effects of light and pCO2 on growth, CO2-fixation and N2-fixation rates by strains of the unicellular marine N2-fixing cyanobacterium Crocosphaera... -
Colimitation of the unicellular photosynthetic diazotroph Crocosphaera watson...
We describe interactive effects of total phosphorus (total P = 0.1-4.0 µmol/L; added as H2NaPO4), irradiance (40 and 150 µmol quanta/m**2/s), and the partial pressure of carbon... -
Seawater carbonate chemistry and diatom aggregation when exposed to crude oil...
Roller table experiments with Thalassiosira pseudonana, a small centric diatom, were conducted to produce marine snow aggregates in six treatments: Control (pCO2 = 400 ppm), OA...
