==THE CONTRIBUTION OF NATURAL VARIABILITY TO THE MODERN DECREASE IN FORAMINIFERAL δ<sup>18</sup>O==
 +
 +
[[Image:Climate_of_the_Past_front.jpg‎|left|80px|]]<font size="2">
 +
We evaluate the contribution of natural variability to the modern decrease in foraminiferal δ<sup>18</sup>O by relying on a 2200-yr-long, high-resolution record of oxygen isotopic ratio from a Central Mediterranean sediment core. Pre-industrial values are used to train and test two sets of algorithms that are able to forecast the natural variability in δ<sup>18</sup>O over the last 150 yr. These algorithms are based on autoregressive models and neural networks, respectively; they are applied separately to each of the δ<sup>18</sup>O series' significant variability components, rather than to the complete series. ......

== A METHOD OF EVALUATING PREHISTORIC GOUNDWATER ON COASTAL CARBONATE TERRAIN ==
 +
 +
[[Image:Marine_Micropaleontology_Front.gif‎|left|80px| ]]<font size="2">
 +
...... Subfossil benthic foraminifera in underwater caves are an overlooked method of evaluating prehistoric groundwater on coastal carbonate terrain because they provide a proxy for groundwater salinity and circulation. Twelve radiocarbon dates and foraminiferal paleoecology from two sediment cores obtained from Green Bay Cave (GBC), Bermuda, provide the first Holocene-scale groundwater reconstruction. First, the cave floor (− 20.7 mbsl) was flooded at ~ 7.7 ka as North Atlantic sea level and groundwater rose in near synchrony. Over the Holocene, groundwater conditions (salinity, circulation and degree of oxygenation) shifted a minimum of five times, primarily in response to sea-level rise. Most importantly, we provide evidence that a prehistoric meteoric lens collapsed at ~ 1.6 ka as sea-level rise breached a local sill and completely altered Bermudian coastal circulation. The complete loss, or retreat, of a groundwater mass associated with a minor sea-level change validates some numerical predictions that small changes in sea level can destabilize coastal groundwater resources, when coastal geometry and circulation are considered.

== PALEOENVIRONMENTAL RECONSTRUCTION FOR THE EARLY PLIOCENE MAGDALENA PALEODELTA, COLOMBIA  ==
 +
 +
<font size="2">
 +
The Magdalena river transports one of the largest load of sediments per basin area in the world. Its delta position has changed several times over the Neogene. The Arroyo Piedras Section (169 m) in northern Colombia, contains part of the record of the Late Miocene to Early Pliocene evolution of the Magdalena paleodelta. ...... Based on lithofacies and benthic foraminifera content, the section was divided in three segments, and the upper segment was dated as Early Pliocene using planktonic foraminifera. The lower segment suggests siliciclastic sedimentation in a proximal prodelta/delta plain transitional environment. The intermediate segment suggests sedimentation in a lagoon and/or coastal swamp environment, whereas the upper segment is interpreted as the result of a transgression and subsequent deposition at the foreshore / upper shoreface environment, with a considerable decrease of terrigenous input. The decrease of sediment delivery to the delta produced by permanent El Niño- like conditions coupled with autocyclic processes could explain the transgressive pattern observed in the Arroyo de Piedras section during the Early Pliocene.

==NEW ECOSTRATIGRAPHIC TOOL WITH POTENTIAL FOR DETECTING PALAEOENVIRONMENTAL CHANGE==

[[Image:PPP_front.gif‎‎|left|80px| ]]<font size="2">
 +
The percent carrying capacity ''K<sub>p</sub>'' is the equilibrium population in percentage terms of a species that an area can support while adequately meeting the needs of every individual. ...... Points of change from one value of ''K<sub>p</sub>'' to another in a stratigraphic section mark regime shifts and have potential for ecostratigraphic correlation. Within the Upper Quaternary of ODP Hole 1006A they apparently reflect an increase in the organic matter flux in the uppermost part of the section. The method described here can be applied to any species in any taxon for which percentage data are available. For those in the hydrocarbon industry it should prove especially useful for detailed studies of intervals of economic interest.

==THRESHOLD OF CARBONATE SATURATION STATE DETERMINED BY CO<sub>2</sub> CONTROL EXPERIMENT==
 +
 +
[[Image:Biogeosciences_front.jpg‎‎|left|80px| ]]<font size="2">
 +
...... Recent reports demonstrate nocturnal carbonate dissolution of reefs, despite a Ω<sub>a</sub> (aragonite saturation state) value of >1. This is probably related to the dissolution of reef carbonate (Mg-calcite), which is more soluble than aragonite. However, the threshold of Ω for the dissolution of natural sediments has not been clearly determined. We designed an experimental dissolution system with conditions mimicking those of a natural coral reef, and measured the dissolution rates of aragonite in corals, and of Mg-calcite excreted by other marine organisms, under conditions of Ω<sub>a</sub> > 1, with controlled seawater pCO<sub>2</sub>. The experimental data show that dissolution of bulk carbonate sediments sampled from a coral reef occurs at Ωa values of 3.7 to 3.8. Mg-calcite derived from foraminifera and coralline algae dissolves at Ω<sub>a</sub> values between 3.0 and 3.2, and coralline aragonite starts to dissolve when Ω<sub>a</sub> = 1.0. We show that nocturnal carbonate dissolution of coral reefs occurs mainly by the dissolution of foraminiferans and coralline algae in reef sediments.

==STABLE-ISOTOPE STRATIGRAPHY OF THE PLIOCENE-PLEISTOCENE CLIMATE TRANSITION IN THE NORTH PACIFIC==

[[Image:PPP_front.gif‎‎|left|80px| ]]<font size="2">
 +
From Ocean Drilling Program (ODP) Site 1208 on Shatsky Rise below the Kuroshio Current Extension, we present the North Pacific's first orbital-scale benthic-foraminiferal δ<sup>18</sup>O and δ<sup>13</sup>C time series to span the Pliocene–Pleistocene climate transition. Excellent agreement between the Site 1208 δ<sup>18</sup>O record and the global δ<sup>18</sup>O stack of Lisiecki and Raymo (2005) provides orbital-scale age control and confirms continuous stratigraphy from 3.7 to 1.8 Ma at the single-hole site. Cross-spectral analysis of the δ<sup>18</sup>O and δ<sup>13</sup>C time series reveals that these are coherent to 80% confidence at the 41-kyr obliquity band prior to 3.3 Ma (glacial isotope stage M2) and increase to the 95% level thereafter. ...... Firm establishment of orbital-scale age control on the stratigraphically complete Site 1208 section now provides a platform for high-resolution paleoceanographic reconstruction of the relatively understudied North Pacific.

==EARLY HOLOCENE LARGE-SCALE MELTWATER DISCHARGE FROM GREENLAND==
 +
 +
[[Image:PPP_front.gif‎‎|left|80px| ]]<font size="2">
 +
Records of foraminiferal assemblages combined with lithological properties (grain size, magnetic parameters and XRF data) of marine sediment cores from West Greenland coastal waters and the adjacent Labrador Sea document widespread early Holocene meltwater discharge. This discharge is concluded to originate from large-scale melting of the Greenland Ice Sheet (GIS) having started prior to 8,600 cal. yr BP and ended at about 7,700-7,500 cal. yr BP, when the GIS margin had withdrawn from the fjords and become mainly land-based. ...... The oceanic regime off West Greenland prior to ~ 7,800 cal. yr BP was thus characterised by the presence of a permanent and widespread meltwater surface layer, presumably preventing deep convection in this region. Apart from indications of a slight decrease in meltwater discharge by the benthic foraminiferal fauna data, neither of the records shows any clear signal of a regionally important 8.2 ka event.

== RESPONSE OF SHELF ECOSYSTEMS TO AN EARLY HOLOCENE HUMID PHASE ==
 +
 +
[[Image:Marine_Micropaleontology_Front.gif‎|left|80px| ]]<font size="2">
 +
Benthic foraminiferal data as well as stable oxygen and carbon isotope records of different planktonic and benthic foraminifera from a shelf sediment core off southwest Mallorca document major sedimentological, hydrological and trophic changes during the Holocene. The Holocene relative sea-level rise resulted in the progradation of different sediment facies types characterized by specific benthic foraminiferal assemblages. This succession reflects the evolution from an unstable shelf ecosystem with high-energy conditions at the sea-floor in the earlier Holocene to a more stable shelf ecosystem in the middle and late Holocene. Between approximately 10.3 and 5.5 kyr BP, low δ<sup>13</sup>C values of the surface dweller ''Globigerinoides ruber'' (white) and high difference in δ<sup>13</sup>C values between the epifaunal ''Cibicides lobatulus'' and the infaunal ''Bulimina aculeata'' document enhanced input of nutrients in surface waters and high remineralisation rates at the sea floor. The trophic change is associated with a change in sediment facies and can be attributed to higher precipitation and consequently, higher nutrient supply via riverine runoff from the island, mainly during the late summer/early fall season. This early Holocene humid interval is nearly contemporaneous to the formation of sapropel S1 in the eastern Mediterranean Sea and the African Humid Period.

==FAUNAL RESPONSE TO RAPID CHANGES OF THE RIVER INFLUENCE, RHÔNE  PRODELTA==

[[Image:Biogeosciences_front.jpg‎‎|left|80px| ]]<font size="2">
 +
In the context of the French research project CHACCRA (Climate and Human-induced Alterations in Carbon Cycling at the River-seA connection), living (rose Bengal-stained) benthic foraminifera were investigated at two stations (24 and 67 m depth) in the Rhône prodelta (NW Mediterranean, Gulf of Lions). The aim of this study was to precise the response of benthic foraminiferal faunas to temporal changes of the Rhône River inputs (e.g. organic and terrigeneous material). Each site was sampled in April 2007, September 2007, May 2008 and December 2008, permitting to observe foraminiferal faunas of the 63–150 and >150 μm size fractions under a wide range of environmental conditions. Obvious variations in foraminiferal faunal composition were observed during the four investigated periods at the shallowest Station A located in the close vicinity of the Rhône River mouth. ...... This study put into evidence the extremely rapid response of benthic foraminiferal faunas to strong variations in environmental conditions mostly induced by the Rhône dynamics.

==SEASONAL AND INTERANNUAL CHANGES OF PLANKTIC FORAMINIFERAL FLUXES IN THE GULF OF LIONS==
 +
 +
[[Image:DeepSeaResearch_I_front.gif‎|left|80px| ]]<font size="2">
 +
In order to investigate the seasonal and interannual variability of planktic foraminifer fluxes in the NW Mediterranean, 266 samples from two 12-year-long sediment traps were analyzed. Two mooring lines were deployed at the east (Station Planier) and the west (Station Lacaze Duthiers) of the Gulf of Lions. The moorings were deployed at a water depth of around 1000 m and were equipped with sediment traps at 500 m above bottom (mab). In addition, an array of 13 core-tops recovered from different key areas of the Gulf of Lions is described. ...... <br/>

► Planktic foraminiferal flux was analyzed in the NW Mediterranean over a 12-yr period. ► Most foraminiferal shells are exported during the winter-spring transition. ► The highest fluxes are recorded in the station affected by the Rhone plume. ► The closest analogs are the core tops located nearby the sediment traps.

This study defines criteria for the use of benthic foraminifera (protists) as a quick and efficient bio-monitoring tool to implement marine legislation. Various sampling and preparation procedures are investigated in an attempt to find the optimal methodology for environmental monitoring using soft-sediment foraminifera with the objective of assessing ecological quality status (EcoQS). Twenty-seven sampling stations in silled basins along the Norwegian Skagerrak coast, NE North Sea, are investigated for environmental parameters and living (stained, including soft-shelled forms) and dead benthic foraminifera. ...... <br/>

The present study investigated the effects of ocean acidification and temperature increase on ''Neogloboquadrina pachyderma'' (sinistral), the dominant planktonic foraminifer in the Arctic Ocean. Due to the naturally low concentration of CO<sub>3</sub><sup>2−</sup> in the Arctic, this foraminifer could be particularly sensitive to the forecast changes in seawater carbonate chemistry. To assess potential responses to ocean acidification and climate change, perturbation experiments were performed on juvenile and adult specimens by manipulating seawater to mimic the present-day carbon dioxide level and a future ocean acidification scenario (end of the century) under controlled (in situ) and elevated temperatures (1 and 4 °C, respectively). ......

==EARLY PALEOGENE GLOBAL DIVERSITY PATTERNS OF LARGE BENTHIC FORAMINIFERA==

 +
<font size="2">
 +
Large benthic foraminifera (LBF) were major contributors to many Paleogene carbonate platforms around the world. These photosymbiotic foraminifera lived in warm, oligotrophic, shallow waters within the photic zone. Such Paleogene families as the nummulitids, alveolinids, and orthophragminids rose to prominence in the late Paleocene, thrived in the early and middle Eocene, and declined in the late Eocene and Oligocene. Diversity data from these three families were studied to understand better the controls on the rise of Paleogene LBFs. Analyzed data included total diversity (total number of species per biozone), number of first occurrences per biozone, and number of last occurrences per biozone. Results indicate that there were four intervals of increased total diversity, increased first occurrence, and increased last occurrence for all three families studied. ......

==ARRIVAL AND EXPANSION OF INVASIVE FORAMINFIERA IN PADILLA BAY, WASHINGTON==
 +
 +
<font size="2">
 +
''Trochammina hadai'' Uchio, a benthic foraminifera native to Japanese estuaries, was first identified as an invasive in 1995 in San Francisco Bay and later in 16 other west coast estuaries. To investigate the timing of the arrival and expansion of this invasive species in Padilla Bay, Washington, we analyzed the distribution of foraminifera in two surface samples collected in 1971, in nine surface samples collected by Scott in 1972–1973, as well as in two cores (Padilla Flats 3 and Padilla V1/V2) obtained in 2004. ...... based on ''T. hadai'''s first appearance occurring stratigraphically well above sedimentological changes in the cores that reflect deposition of sediments in the bay due to previous diversions of the Skagit River, and its dominance in the early 1970s surface samples, we conclude that the species arrived in Padilla Bay somewhere between the late 1800s and 1971. ''Trochammina hadai'' may have been introduced into the bay in the 1930s when oyster culturing began there or, at a minimum, ten years prior to its appearance in San Francisco Bay.
