Timing of calcification and environmental variability determine pH proxy fidelity in coastal calcifying macroalgae

Limnology and Oceanography, EarlyView.
Abstract Long‐lived calcifying marine biota are increasingly used as paleo‐archives for reconstructing ocean pH. They enable exploration of the rate and magnitude of ocean acidification in shallow‐water ecosystems serving as proxies for environmental pH reconstruction.

Anthropogenic infilling of a Bermudian sinkhole and its impact on sedimentation and benthic foraminifera in the adjacent anchialine cave environment

International Journal of Speleology, 2017
In the mid-20th century, an inland brackish pond from Bermuda, known as Eve’s Pond, was filled with marine sediment from an adjacent coastal lagoon. At this time, an eyewitness reported “…sediment billowing out of the Green Bay Cave for days…”, which is ...

Bleaching-Associated Changes in the Microbiome of Large Benthic Foraminifera of the Great Barrier Reef, Australia

Frontiers in Microbiology, 2018
Ocean warming is known to cause detrimental effects in coral reef fauna that rely on photo-symbiosis for survival. Microbial associations can facilitate the success of species across a range of environmental conditions, and play a role in the capacity of

Calcium isotopic composition of high-latitude proxy carrier Neogloboquadrina pachyderma (sin.) [PDF]

, 2009
The accurate reconstruction of sea surface temperature (SST) history in climate-sensitive regions (e.g. tropical and polar oceans) became a challenging task in palaeoceanographic research.

Harnessing nature's buffer: Assessing the role of bivalve shells in coastal alkalinity regeneration

Limnology and Oceanography Letters, EarlyView.
Abstract Bivalve shells, a natural alkaline material, play a crucial role in coastal carbon cycles by influencing total alkalinity (TA) and dissolved inorganic carbon (DIC). This study investigated oyster shell dissolution in Narragansett Bay, Rhode Island, under varying pCO2 conditions, revealing TA regeneration rates of 4–56 μmol L−1 d−1, which could

Early to middle Miocene foraminifera from the deep-sea Congo Fan, offshore Angola [PDF]

, 2008
Analysis of a 630m section of an exploration well penetrating the distal part of the Congo Fan (~2000m water depth) yielded high abundance and diversity assemblages of agglutinated and calcareous benthic foraminifera.

Silicate weathering and carbon cycle controls on the Oligocene-Miocene transition glaciation [PDF]

, 2017
Changes in both silicate weathering rates and organic carbon burial have been proposed as drivers of the transient “Mi-1” glaciation event at the Oligocene-Miocene transition (OMT; ~23 Ma).

Shifting microbial communities in acidified seawaters: insights from polychaetes living in the CO2 vent of Ischia, Italy

Integrative Zoology, EarlyView.
The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

The Campanian–Maastrichtian foraminiferal biostratigraphy of the basement sediments from the southern Pannonian Basin (Vojvodina, northern Serbia): implications for the continuation of the Eastern Vardar and Sava zones

Geologica Carpathica, 2017
Micropalaeontological and biostratigraphical studies included Campanian-Maastrichtian complexes from five oil exploration wells drilled in northern Serbia (Vojvodina): the first is a carbonate-clastic complex and second is a complex containing ophiolites

Bioestratigrafia do Oligoceno Inferior-Mioceno Inferior da Formação Asmari, Flanco Sul do Anticlinal Mish, Zona Izeh, SW Irã [PDF]

Anuário do Instituto de Geociências, 2018
In this research, biostratigraphy related to the Asmari Formation at the southern flank of Mish anticline, Izeh Zone, is discussed. In the studied stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies Quaternary ...
