Abstract: We conducted a 93-day experiment investigating the independent and combined effects of acidification (280−3300 µatm pCO2) and warming (28°C and 31°C) on calcification and linear extension rates of four key Caribbean coral species (Siderastrea siderea, Pseudodiploria strigosa, Porites astreoides, Undaria tenuifolia) from inshore and offshore reefs on the Belize Mesoamerican Barrier Reef System. All species exhibited nonlinear declines in calcification rate with increasing pCO2. Warming only reduced calcification in Ps. strigosa. Of the species tested, only S. siderea maintained positive calcification in the aragonite-undersaturated treatment. Temperature and pCO2 had no effect on the linear extension of S. siderea and Po. astreoides, and natal reef environment did not impact any parameter examined. Results suggest that S. siderea is the most resilient of these corals to warming and acidification owing to its ability to maintain positive calcification in all treatments, Ps. strigosa and U. tenuifolia are the least resilient, and Po. astreoides falls in the middle. These results highlight the diversity of calcification responses of Caribbean corals to projected global change. Category: geoscientificInformation Source: Not Available Supplemental Information: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2019) was used to compute a complete and consistent set of carbonate system variables, as described by Nisumaa et al. (2010). In this dataset the original values were archived in addition with the recalculated parameters (see related PI). The date of carbonate chemistry calculation by seacarb is 2020-03-18.

Abstract: Data from Murtinheira section at Cabo Mondego in Portugal. The section is dated from the upper Aalenian to the lower Bajocian (Middle Jurassic). Samples are labelled CN. Phosphorus content quantification was based on the ascorbic acid method (Mort et al., 2007) using a Perkin UV/Vis spectrophotometer Lambda 25. The concentration of PO4 was determined by calibration of BD47 and NU81 standards. TOC was measured after decarbonatization using an elementary analyzer Thermo-Finnigan Flash EA 1112. d13C organic carbon was measured using a Thermo Fischer Scientific Delta V isotope ratio mass spectrometer. d13C-d18O carbonate was measured using a Multiprep auto-sampler coupled to a GV Isoprime mass spectrometer calibrated based on NIST NBS19. CaCO3 content was measured using a Dietrich-Frühling calcimeter based on measuring the CO2 evolved after acidification of a sample.

Abstract: In the present study, we collected data on biofouling in 17 marinas along the Baltic Sea coast during three consecutive boating seasons (May-October 2014, 2015 and 2016). In this context, we compared different monitoring strategies and developed a fouling index (FI) to characterise marinas according to the recorded biofouling abundance and type (defined according to the hardness and strength of attachment to the substrate). Lower FI values, i.e. softer and/or less abundant biofouling, were consistently observed in marinas in the north-eastern Baltic Sea. The decrease in FI from the south-western to the north-eastern Baltic Sea was partially explained by the concomitant decrease in salinity. Nevertheless, most of the observed changes in biofouling seemed to be determined by local factors and inter-annual variability, which emphasizes the necessity for systematic monitoring of biofouling by end-users and/or authorities for the effective implementation of non-toxic antifouling alternatives in marinas.

Abstract: The data were generated at ESRF beamline ID22 with an incident energy at 17 keV. Coccoliths were analyzed with 0.1 µm x 0.1 µm pixel size and 2 s time analysis per pixel. All coccoliths were picked from samples from Murtinheira section at Cabo Mondego, Portugal dated to the lower Bajocian (Middle Jurassic). Discorhabdus striatus1 from sample CM9; Watznaueria britannica1-Watznaueria britannica2 from sample CM17 ; Discorhabdus striatus2 from sample CM26; Discorhabdus striatus3-Watznaueria britannica3-Watznaueria britannica4-Watznaueria contracta from sample CM35 ; Discorhabdus striatus4-Watznaueria indet.1-Watznaueria indet.2 from sample CM60 ; Watznaueria britannica5-Watznaueria britannica6-Watznaueria britannica7 from sample CM62. Data treatment is made using PyMCA. For each calcareous nannofossil, the raw data (.edf in .zip) and the pondered spectrum (.csv) are given. The fit file given (.cfg) may be used for all coccoliths. Those data were acquired through the project EC811 at ESRF.

Abstract: Recent culture studies of living coccolithophores have established a biogeochemical framework for the use of the geochemical compositions of their calcite biominerals as proxies in palaeoceanography. Yet, questions remain regarding the transferability of such experimental data to fossil coccoliths. Here we analysed the carbon and oxygen isotopic composition of Miocene coccoliths to assess the suitability of such data for reconstructing the past environment. We found that the oxygen isotopic compositions of the relatively small Noelaerhabdaceae coccoliths gathered in the 3-5 μm fractions appear to be a suitable material to derive temperatures after a correction for a constant vital offset of 0.8‰. The interpretation of the isotopic signal of the relatively large Coccolithales coccoliths (5-8 μm fractions) is more complex, but supports results from cultures. The expression of the carbon and oxygen vital effect in coccoliths appears to be limited during the so-called Miocene Climate Optimum (MCO), a period of relatively elevated atmospheric pCO~2~. Subsequently, during the Miocene Climatic Transition (MCT; 14 Ma), which saw a decline in pCO~2, large carbon and oxygen vital effects were expressed in coccolith calcite. This phenomenon predates the postulated “Late Miocene Threshold” by approximately 4 Ma, and cannot be reconciled as a temporally-synchronous nor localised feature. Furthermore, we observed a statistically significant correlation between the oxygen and carbon offsets of the small relative to large coccoliths (hence, the vital effect per se) that is likely linked to variations in atmospheric CO~2~. This biogeochemical correlation further supports a forcing of the environment on the cellular physiology (growth rate and utilisation of intracellular carbon) and ultimately the magnitude of isotopic vital effects in fossil coccoliths.

Abstract: Anemonefish species are iconic tropical reef fish which occur in many recreational tourism hotspots. They tend to be highly territorial of their host anemone and display many behaviours relating to their purpose in defending it. Territorial behaviours of two anemonefish species (Amphiprion clarkii and Amphiprion melanopus) were observed in six anemones via snorkeler observation, stimulating observer presence. A GoPro was used to record behaviours in the absence of humans. Other factors including tourism level (0; no tourism - 8; high tourism), the number of fish in the anemone, anemone species, anemone depth (by dive computer) and fish size (by visual approximation) were also measured to examine in relation to fish behaviours. Data was collected off the coast of Efate island in Vanuatu (17° 44' 5'' S, 168° 19' 19'' E) from 5 to 26 January, 2019. For each sample, two anemones at least 20 metres apart (either Entacmaea quadricolor or Heteractis crispa) were selected. At each anemone, a GoPro camera was set up with a view of the entire anemone. At anemone 1, observer presence was simulated by hovering 1-3 metres over the anemone. The GoPro recorded anemonefish behaviours at anemone 2 in the absence of observers. The first 2 minutes of GoPro footage was disregarded from observer absence recordings to reduce possible influence of deployment. The subsequent 15 minutes were used for observation from both anemones. Behaviours of all anemonefish in both anemones were observed. In total, 21 fish were sampled from six anemones. From GoPro video footage from both observer presence and absence recordings, fish behaviour was noted every 15 seconds for each fish individual. In total, 60 behaviour events were recorded for each anemonefish in both observer presence and absence.
