title: Charcoal concentration of sediment core LMAHA-18 from lake Mahasarika, northern Madagascar

description: The datasets provided here correspond to sedimentary charcoal counts, magnetic susceptibility measurements, and δ13C isotopic measurements obtained from a lacustrine sediment core recovered from Lake Maharasika in Montagne d'Ambre (northern Madagascar, 1,073 m asl). Fieldwork has been carried out in August 2018. The sediment core LMAHA-18 was taken from the central and deepest part of the lake (7 m water depth; 12.53509S, 49.17701E). Core LMAHA-18 was sampled with a Livingstone piston sediment corer operated from a small platform settled on two rubber boats. Using sampling tubes of ca. 5 cm diameter and 120 cm length, a total of 6 sections of about 100 cm sediment length were sampled with overlaps of 10-50 cm length. Preserved in aluminium tubes for transport to the laboratory, sediment was extruded from each aluminium tube and split into two sister cores, LMAHA-18a and LMAHA-18b. Each sister core was stored under cool (4°C) and dark conditions at the laboratory facilities (LMAHA-18a at the Friedrich-Schiller-University Jena and LMAHA-18b at the University of Goettingen, Germany).For extraction of charcoal particles, 1 cm3 of sediment was taken every cm along the LMAHA-18 core. Each sample was soaked in a 3% NaP2O4 solution plus bleach for several hours to deflocculate the sediment and oxidise organic matter. The samples were sieved through a 160 μm mesh and the carbon particles were counted using a x40 magnification stereomicroscope.

title: Seawater carbonate chemistry and Microzooplankton and phytoplankton community composition of KOSMOS 2013 Gullmar Fjord mesocosm study

description: Ocean acidification is considered as a crucial stressor for marine communities. In this study, we tested the effects of the IPCC RPC6.0 end-of-century acidification scenario on a natural plankton community in the Gullmar Fjord, Sweden, during a long-term mesocosm experiment from a spring bloom to a mid-summer situation. The focus of this study was on microzooplankton and its interactions with phytoplankton and mesozooplankton. The microzooplankton community was dominated by ciliates, especially small Strombidium sp., with the exception of the last days when heterotrophic dinoflagellates increased in abundance. We did not observe any effects of high CO2 on the community composition and diversity of microzooplankton. While ciliate abundance, biomass and growth rate were not affected by elevated CO2, we observed a positive effect of elevated CO2 on dinoflagellate abundances. Additionally, growth rates of dinoflagellates were significantly higher in the high CO2 treatments. Given the higher Chlorophyll a content measured under high CO2, our results point at mainly indirect effects of CO2 on microzooplankton caused by changes in phytoplankton standing stocks, in this case most likely an increase in small-sized phytoplankton of &lt;8 μm. Overall, the results from the present study covering the most important part of the growing season indicate that coastal microzooplankton communities are rather robust towards realistic acidification scenarios.
description: In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Gattuso et al, 2021) 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 2023-02-28.
