Abstract The cycling of biologically produced calcium carbonate (CaCO 3 ) in the ocean is a fundamental component global carbon cycle. Here, we present experimental determinations situ coccolith and foraminiferal calcite dissolution rates. We combine these rates with solid phase fluxes, dissolved tracers, historical data to constrain alkalinity cycle shallow North Pacific Ocean. coccolithophores demonstrate nonlinear dependence on saturation state. Dissolution all three major calcifying...
Abstract Planktonic calcifying organisms play a key role in regulating ocean carbonate chemistry and atmospheric CO 2 . Surprisingly, references to the absolute relative contribution of these calcium production are lacking. Here we report quantification pelagic North Pacific, providing new insights on three main planktonic groups. Our results show that coccolithophores dominate living (CaCO 3 ) standing stock, with coccolithophore calcite comprising ~90% total CaCO production, pteropods...
Abstract Anthropogenic carbon dioxide emissions directly or indirectly drive ocean acidification, warming and enhanced stratification. The combined effects of these processes on marine planktic calcifiers at decadal to centennial timescales are poorly understood. Here, we analyze size normalized foraminiferal shell weight, geochemistry, supporting proxies from 3 sediment cores in the Mediterranean Sea spanning several centuries. Our results allow us investigate response surface-dwelling...
The increase in anthropogenic induced warming over the last two centuries is impacting marine environment.Planktic foraminifera are a globally distributed calcifying zooplankton responding sensitively to changes sea surface temperatures and interacting with food web structure.Here, we study high resolution multicore records from western Mediterranean Sea regions (Alboran Balearic basins), areas highly affected by both natural climate change warming.Cores cover time interval Medieval Climate...
Abstract Marine functional connectivity (MFC) refers to the flows of organic matter, genes, and energy that are caused by active passive movements marine organisms. Occurring at various temporal spatial scales, MFC is a dynamic, constantly evolving global ecological process, part overall connectivity, but with its own distinct specific patterns. Geological historical archives changes in distributions, life histories, migration species can provide baselines for deciphering long-term trends...
<p>The increase in anthropogenic induced warming over the last two centuries is impacting marine environments. Marine planktic calcifying organisms interact sensitively to changes sea surface temperatures (SST), and food web structure. Here, we study high resolution multicore records from western Mediterranean Sea regions (Alboran Balearic basins), areas highly affected by both natural climate change warming. Cores cover time interval Medieval Climate Anomaly (MCA) present....
