     14abstract = {{The Atlantic and Arctic Oceans are critical components of the global carbon cycle. Here we quantify the net sea-air {CO$_{2}$} flux, for the first time, across different methodologies for consistent time and space scales for the Atlantic and Arctic basins. We present the long-term mean, seasonal cycle, interannual variability and trends in sea-air {CO$_{2}$} flux for the period 1990 to 2009, and assign an uncertainty to each. We use regional cuts from global observations and modeling products, specifically a p{CO$_{2}$}-based {CO$_{2}$} flux climatology, flux estimates from the inversion of oceanic and atmospheric data, and results from six ocean biogeochemical models. Additionally, we use basin-wide flux estimates from surface ocean p{CO$_{2}$} observations based on two distinct methodologies. Our estimate of the contemporary sea-air flux of {CO$_{2}$} (sum of anthropogenic and natural components) by the Atlantic between 40\degre S and 79\degre N is -0.49 $\pm$ 0.05 Pg C yr-1, and by the Arctic it is -0.12 $\pm$ 0.06 Pg C yr-1, leading to a combined sea-air flux of -0.61 $\pm$ 0.06 Pg C yr-1 for the two decades (negative reflects ocean uptake). We do find broad agreement amongst methodologies with respect to the seasonal cycle in the subtropics of both hemispheres, but not elsewhere. Agreement with respect to detailed signals of interannual variability is poor, and correlations to the North Atlantic Oscillation are weaker in the North Atlantic and Arctic than in the equatorial region and southern subtropics. Linear trends for 1995 to 2009 indicate increased uptake and generally correspond between methodologies in the North Atlantic, but there is disagreement amongst methodologies in the equatorial region and southern subtropics.}},

Results compare well with the widely used monthly climatology by Takahashi et al. (2009) but also contain some short-term and interannual variations. Fitting the same model to atmospheric {CO$_{2}$} data yields less robust but consistent estimates, confirming that using the partial pressure based estimates as ocean prior in atmospheric {CO$_{2}$} inversions may improve land {CO$_{2}$} flux estimates. Estimated seasonality of ocean-internal carbon sources and sinks is discussed in the light of observed nutrient variations.}},

    26522726abstract = {{The {R}ock-{E}val pyrolysis technique was first developed as a rapid mean for evaluating the petroleum potential of source rocks, via the measurement of bulk organic parameters such as {T}otal {O}rganic {C}arbon (TOC), {H}ydrogen {I}ndex (HI), {O}xygen {I}ndex (OI) and the maximum pyrolysis temperature {T}max (Espitalié et al., 1985; {L}afargue et al., 1998). {T}his method was then used to rapidly estimate organic matter quality and quantity in sedimentary series for paleoenvironmental studies (Talbot and {L}ivingston, 1989). {R}ecently, it has been proposed that there could be more information gained from the {R}ock-{E}val parameters (Disnar et al., 2003). {W}hen considering also the recent analytical developments available from the {T}urbo6 version of the apparatus, there is a large field of investigation that remains unexplored in paleoenvironmental studies. {H}ere we present results from the sedimentary infill of {L}agoa do {C}açó (Northern {B}razil) that records paleoenvironmental changes since the {L}ast {G}lacial {M}aximum (Jacob et al., 2004). {T}he present study focuses on the {L}ateglacial interval (ca. 17,000 to 11,000 cal yrs BP), a time period where different {R}ock-{E}val parameters such as {T}pS2 (Tmax equivalent), HI and OI produce controversial information. {I}n order to better understand the meaning of these parameters, we propose an original mean of obtaining more pertinent information. S3CO2/S3CO ratio and {T}pS2 surprisingly display similar trends over the considered period, in two different cores. {F}urthermore, the evolution of these parameters is comparable with that of #18O in the ice core record of {S}ajama (Bolivia) during the {L}ateglacial (Figure 1). {A}lthough the significance of these parameters and the origin of these variations remain to be cleared, our results confirm a pattern of rapid climate variability over the {S}outh {A}merican {T}ropics during the last deglaciation, as seen in the {N}orthern {H}emisphere.}},

    26872761abstract = {{Ecosystems and populations are known to be influenced not only by long-term climatic trends, but also by other short-term climatic modes, such as interannual and decadal-scale variabilities. {B}ecause interactions between climatic forcing, biotic and abiotic components of ecosystems are subtle and complex, analysis of long-term series of both biological and physical factors is essential to understanding these interactions. {H}ere, we apply a wavelet analysis simultaneously to long-term datasets on the environment and on the populations and breeding success of three {A}ntarctic seabirds (southern fulmar, snow petrel, emperor penguin) breeding in {T}erre {A}délie, to study the effects of climate fluctuations on {A}ntarctic marine ecosystems. {W}e show that over the past 40 years, populations and demographic parameters of the three species fluctuate with a periodicity of 3-5 years that was also detected in sea-ice extent and the {S}outhern {O}scillation {I}ndex. {A}lthough the major periodicity of these interannual fluctuations is not common to different species and environmental variables, their cyclic characteristics reveal a significant change since 1980. {M}oreover, sliding-correlation analysis highlighted the relationships between environmental variables and the demography of the three species, with important change of correlation occurring between the end of the 1970s and the beginning of the 1980s. {T}hese results suggest that a regime shift has probably occurred during this period, significantly affecting the {A}ntarctic ecosystem, but with contrasted effects on the three species.}},

    33913465abstract = {{N}ortheast {B}razil represents a key area in terms of {H}olocene environmental changes in {S}outh {A}merica due to its distinct semi-arid climate at near equatorial latitudes as well as to a wetter {E}arly and {M}iddle {H}olocene paleoclimate in comparison with other {S}outh {A}merica regions, which also experienced a reduced monsoon at that time. {W}e studied the lacustrine sediments of {L}ake {B}oqueirão, which is located at 5°S latitude on the {B}razilian {A}tlantic coast; it is directly influenced by displacement of the {I}ntertropical {C}onvergence {Z}one (ITCZ). A short (1 m) core "Boqc0701" was collected at a 7.5 m water depth during a seismic survey. {O}rganic matter (OM) geochemical [Rock {E}val {T}otal {O}rganic {C}arbon (TOC), {H}ydrogen {I}ndex (HI), {O}xygen {I}ndex (OI)] and petrographical studies allowed us to distinguish five sedimentary intervals during the last 3 kyrs. {P}hase E (3000 to 2050 cal yr BP) presents the largest TOC, HI and OI fluctuations in the entire core. {T}he most probable cause of these variations is a great instability in the lake level during this period. {P}hase D (2050 to 1830 cal yr BP) is marked by an increase in sedimentation rate and a higher contribution from a well-preserved OM with an algal origin; this was interpreted as a higher and more stable lake level. {D}uring phase C (1830 to 1550 cal yrs BP), low HI and high OI indicate the input of more oxidized, degraded and detrital OM, reflecting a lower lake level. {I}n phase B (1550 to 1470 cal yr BP), the OM quality and quantity (HI and TOC) indicate an algal contribution. {D}uring phase A (1470 to 570 cal yr BP), the high stability of the proxies may be due to a deep environment where OM fluctuations are strongly buffered. {T}hese changes in lake level can be compared with other tropical {S}outh {A}merica high resolution records. A correspondence seems to exist between phases of low ENSO, cool {N}orth {A}tlantic {O}cean and {B}oqueirão wet phases. {W}e did not encounter this same pattern during the last 1050 yaers, during which the 1050-570 cal yrs BP interval was generally wet (although probable fluctuations are buffered in our proxies) while the {N}orth {A}tlantic was warm (Mann et al., 2009). A prolonged dryness occurred in {L}ake {B}oqueirão from 570 cal yrs BP until recent decades. {T}his phase corresponds to the {L}ittle {I}ce {A}ge characterized by a cooler {N}orth {A}tlantic {O}cean (Mann et al., 2009). {T}hese data indicate that the teleconnection pattern between the tropical {A}tlantic, ENSO and {N}ortheast {B}razil rainfalls has changed in the past.},
