Early instrumental observations are an important tool to understand multidecadal climate variability or put in context specific extreme phenomena. This paper provides early instrumental data recovered in Latin-America and the Caribbean. Data have been retrieved from 20 countries (Argentina, Bahamas, Belize, Brazil, British Guiana, Chile, Colombia, Costa Rica, Cuba, Ecuador, France (Martinique and Guadalupe), Guatemala, Jamaica, Mexico, Nicaragua, Panama, Peru, Puerto Rico, El Salvador and Suriname) and they cover the 18th and 19th centuries.

Meteorological measurements in San José, Costa Rica from January 1866- December 1867, digitized version

Mr Maison
In the observations is highlighted an ash fall in San José in January and February of 1866 (4 and 8 Days respectably). These ashes come from a estrombolean eruptions of the Turrialba volcano in January and February (Volcanic Explosivity Index 3). San José is 45km from Turrialba volcano but during this event ash fall was reported also in Puntarenas (115 km distance to the volcano) (Duarte González, 2014).---The data of this dataset might have been...

Insights fromsodium into the impacts of elevated pCO2 and temperature on bivalve shell formation, supplement to: Zhao, Liqiang; Schöne, Bernd R; Mertz-Kraus, Regina; Yang, Feng (2017): Insights from sodium into the impacts of elevated pCO2 and temperature on bivalve shell formation. Journal of Experimental Marine Biology and Ecology, 486, 148-154

Liqiang Zhao, Bernd R Schöne, Regina Mertz-Kraus & Feng Yang
Ocean acidification and warming are predicted to affect the ability of marine bivalves to build their shells, but little is known about the underlying mechanisms. Shell formation is an extremely complex process requiring a detailed understanding of biomineralization processes. Sodium incorporation into the shells would increase if bivalves rely on the exchange of Na+/H+ to maintain homeostasis for shell formation, thereby shedding new light on the acid-base and ionic regulation at the calcifying front. Here,...

Sodium provides unique insights into transgenerational effects of ocean acidification on bivalve shell formation, supplement to: Zhao, Liqiang; Schöne, Bernd R; Mertz-Kraus, Regina; Yang, Feng (2017): Sodium provides unique insights into transgenerational effects of ocean acidification on bivalve shell formation. Science of the Total Environment, 577, 360-366

Liqiang Zhao, Bernd R Schöne, Regina Mertz-Kraus & Feng Yang
Ocean acidification is likely to have profound impacts on marine bivalves, especially on their early life stages. Therefore, it is imperative to know whether and to what extent bivalves will be able to acclimate or adapt to an acidifying ocean over multiple generations. Here, we show that reduced seawater pH projected for the end of this century (i.e., pH 7.7) led to a significant decrease of shell production of newly settled juvenile Manila clams, Ruditapes...

Seawater carbonate chemistry and Calcium carbonate (CaCO3) sediment dissolution, supplement to: Lantz, Coulson A; Carpenter, Robert C; Edmunds, Peter J (2017): Calcium carbonate (CaCO3) sediment dissolution under elevated concentrations of carbon dioxide (CO2) and nitrate (NO 3?). Journal of Experimental Marine Biology and Ecology, 495, 48-56

Coulson A Lantz, Robert C Carpenter & Peter J Edmunds
Ocean acidification (OA), attributed to the sequestration of atmospheric carbon dioxide (CO2) into the surface ocean, and coastal eutrophication, attributed in part to land-use change and terrestrial runoff of fertilizers, have received recent attention in an experimental framework examining the effects of each on coral reef net ecosystem calcification (Gnet). However, OA and eutrophication in conjunction have yet to receive attention from the perspective of coral reef sediment dissolution. To address this omission, CO2 and...

Seawater carbon chemistry and net primary production and net calcification in coral reef communities, supplement to: Comeau, Steeve; Edmunds, Peter J; Lantz, Coulson A; Carpenter, Robert C (2017): Daily variation in net primary production and net calcification in coral reef communities exposed to elevated CO2. Biogeosciences, 14(14), 3549-3560

Steeve Comeau, Peter J Edmunds, Coulson A Lantz & Robert C Carpenter
The threat represented by ocean acidification (OA) for coral reefs has received considerable attention because of the sensitivity of calcifiers to changing seawater carbonate chemistry. However, most studies have focused on the organismic response of calcification to OA, and only a few have addressed community-level effects, or investigated parameters other than calcification, such as photosynthesis. Light (photosynthetically active radiation, PAR) is a driver of biological processes on coral reefs, and the possibility that these processes...

Effects of pCO2 on spatial competition between the corals Montipora aequituberculata and Porites lutea

Nicolas R Evensen, Peter J Edmunds & Kazuhiko Sakai
We tested the hypothesis that ocean acidification (OA) affects spatial competition among scleractinian corals. Competitive ability was evaluated indirectly by linear extension of Porites lutea and Montipora aequituberculata placed in intraspecific, interspecific, and control pairings (paired with dead coral skeleton) and exposed to ambient (400 µatm) and elevated (1000 µatm) pCO2 in experiments conducted in Moorea, French Polynesia, and Okinawa, Japan. High pCO2 had no effect on linear extension of M. aequituberculata in Moorea, but...

Seawater carbonate chemistry and body size, respiration and photosynthesis of the branching coral Pocillopora verrucosa

Peter J Edmunds & Scott C Burgess
Body size has large effects on organism physiology, but these effects remain poorly understood in modular animals with complex morphologies. Using two trials of a 24 day experiment conducted in 2014 and 2015, we tested the hypothesis that colony size of the coral Pocillopora verrucosa affects the response of calcification, aerobic respiration and gross photosynthesis to temperature (26.5 and 29.7°C) and pCO2 (40 and 1000 µatm). Large corals calcified more than small corals, but at...

Average surface mass balance (SMB) components at 1 km for the Canadian Arctic Archipelago (1958-1995 and 1996-2015), links to RACMO2.3 model results in NetCDF format, supplement to: Noël, Brice P Y; van de Berg, Willem Jan; Lhermitte, Stef; Wouters, Bert; Schaffer, Nicole; van den Broeke, Michiel R (2018): Six decades of glacial mass loss in the Canadian Arctic Archipelago. Journal of Geophysical Research-Earth Surface, 123(6), 1430-1449

Brice P Y Noël
The Canadian Arctic Archipelago (CAA) comprises multiple small glaciers and ice caps mostly concentrated on Ellesmere and Baffin Islands in the northern (NCAA) and southern parts (SCAA) of the archipelago, respectively. Because these glaciers are small and show complex geometries, current regional climate models, using 5 to 20 km horizontal resolution, do not properly resolve surface mass balance (SMB) patterns. Here, we present a 58-year (1958-2015) reconstruction of daily SMB of the CAA, statistically downscaled...

Time-series of snow spectral albedo and superficial snow specific surface area and impurity content at Col de Porte, French Alps, 2014, supplement to: Dumont, Marie; Arnaud, Laurent; Picard, Ghislain; Libois, Quentin; Lejeune, Yves; Nabat, Pierre; Voisin, Didier; Morin, Samuel (2016): In situ continuous visible and near-infrared spectroscopy of an alpine snowpack. The Cryosphere Discussions, 32 pp

Ghislain Picard, Laurent Arnaud & Marie Dumont
Spectral albedo has been measured at Col de Porte from January until end of April 2014 in the visible and near infrared (400 - 1050 nm) at sub-hourly resolution using a home-made spectral radiometer. Calibration follows the procedure described in Picard et al. 2016 (doi:10.5194/tc-10-1297-2016). The specific surface area (SSA) and impurity content (black carbon equivalent) of the superficial snow have been retrieved for clear-sky days using an original methodology described in the companion paper...
