bastidor - From the Lab to the Ocean: Portugal joins global effort to study Ocean Alkalinity Enhancement - Make it stand out Scenes from Day Zero of our OAEPIIP experiment: the day began with the filling of our microcosm tanks with natural seawater collected from Cascais Bay, on Portugal’s west coast. Once filled, the tanks were carefully transported to the temperature-controlled laboratory at FCUL in Lisbon, where the experiment would take place. A special thanks to our project partners João Duarte (IH) and Mário Abel Gonçalves (IDL-FCUL), who played a key role in coordinating the logistics of seawater collection and transport. Thanks to their efforts, all tanks arrived at the lab safely and in perfect condition, ready to kick off the experiment. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/dacb7f9a-056b-48e6-8e44-d1eb80269721/3.+OAEPIIP+Cascais+Day+0+19+May_+in-situ+sampling.jpg Blog - bastidor - From the Lab to the Ocean: Portugal joins global effort to study Ocean Alkalinity Enhancement - Make it stand out In addition to filling the microcosm tanks, our team - including researchers from MARE, IDL, IH and IPMA - also collected seawater samples to characterise the in-situ hydrological and biological conditions in Cascais Bay, providing a valuable baseline for comparison with all experimental data from the tanks. This initial survey included measurements of temperature, alkalinity, pH, and chlorophyll-a concentrations, as well as the collection of plankton community samples. Interestingly, the seawater was marked by a bloom of Mesodinium rubrum — a free-living, red-tide marine ciliate commonly found in coastal waters during spring. This natural event added an extra layer of ecological relevance to our experiment. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/8ec4aa2c-099b-4693-9858-f8aebc880c7d/4.+OAEPIIP+Day+0+Cold+Lab+FCUL_Alkalinity.jpg Blog - bastidor - From the Lab to the Ocean: Portugal joins global effort to study Ocean Alkalinity Enhancement - Make it stand out Day Zero of our microcosm experiment: all nine tanks were set up in their designated positions in front of the light source, inside the temperature-controlled room. To avoid any position-related bias in light or temperature exposure, the tanks were randomly rotated daily throughout the experiment.

(B) After a 24-hour settling period, particles are sampled based on their sinking speeds—slow, moderate, or fast. Sinking speed – to which the coccolith-ballasting effetc can contribute – is key to understanding how efficiently organic material is transported to the deep ocean, which in turn affects long-term carbon storage and the ocean’s role in regulating climate.

This theory sparked a wave of multidisciplinary research sparked over the last decades, exploring data from both in situ and remote monitoring of the ocean, but also from multiples laboratory and ocean experiments investigating the effects of Fe and dust fertilization in the ocean, and from model outputs. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/ffa2075b-3f09-494c-88d4-7fc7de157b65/Screenshot+2024-11-28+at+21.40.36.jpg Blog - bastidor - Catarina Guerreiro presents a plenary keynote on 'Atmospheric deposition and ocean biogeochemistry' at the 9th SOLAS OSC, in Goa, India - Make it stand out Several studies published by our Dusty-Team exploring Saharan dust impacts on the Atlantic Ocean, including micropalaeontologists, marine geologists, marine biologists, oceanographers, atmospheric chemists, and marine biogeochemists from MARE-Ulisboa, IDL, IPMA, NIOZ, MARUM, PML, EAU, ICTA and CSIC-ICM (Guerreiro et al., 2017; 2019; 2021; 2023; 2024; Korte et al., 2017; 2020). https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/dc048582-d4f2-443c-a2e9-76739d839eae/PHOTO-2024-11-20-06-58-57.jpg Blog - bastidor - Catarina Guerreiro presents a plenary keynote on 'Atmospheric deposition and ocean biogeochemistry' at the 9th SOLAS OSC, in Goa, India - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.chase-dust.com/blog-bastidor/federico-malavolta-presents-the-results-from-his-erasmus-at-cincias-ulisboa-at-the-19th-ina-conference-in-wales-uk monthly 0.5 2024-10-04 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/940fe6e1-7629-4b7a-8ffe-c1ed29cb6cde/WhatsApp+Image+2024-09-11+at+18.14.59.jpg Blog - bastidor - Federico Malavolta presents results from his ERASMUS+ at Ciências ULisboa, during the 19th INA Conference, in North Wales (UK) - Make it stand out Federico presenting his very first scientific poster at the 19th INA Conference. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/ad5f4ecd-7ab0-4f87-ab17-749bb6f0fba1/WhatsApp+Image+2024-09-11+at+14.13.58.jpeg Blog - bastidor - Federico Malavolta presents results from his ERASMUS+ at Ciências ULisboa, during the 19th INA Conference, in North Wales (UK) - Make it stand out Federico (on the left) next to two of his co-authors: Mário Cachão (IDL/Ciências ULisboa) and Elisa Malinverno (University of Milano-Bicocca). https://www.chase-dust.com/blog-bastidor/young-researcher-federico-malavolta-collaborates-with-cincias-ulisboa-chasing-for-coccolithophores-across-the-south-atlantic-subtropical-gyre monthly 0.5 2024-08-24 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/70b17d08-521a-4cc6-943c-39aa67b96d05/PHOTO-2024-08-23-18-50-55.jpg Blog - bastidor - Young researcher Federico Malavolta collaborates with Ciências-ULisboa, CHASing for coccolithophores across the South Atlantic Subtropical Gyre! - Make it stand out Federico Malavolta (left) and Catarina Guerreiro (right) in front of the Calcareous Nannoplankton Laboratory, at Ciências-ULisboa, Portugal. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1724435678705-KOKVZS4OS389TBUVIJ46/PHOTO-2024-08-23-18-50-55+3.jpg Blog - bastidor - Young researcher Federico Malavolta collaborates with Ciências-ULisboa, CHASing for coccolithophores across the South Atlantic Subtropical Gyre! https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1724435692871-6Q2LQGAAR63GE5GVNUX2/PHOTO-2024-08-23-18-50-55+2.jpg Blog - bastidor - Young researcher Federico Malavolta collaborates with Ciências-ULisboa, CHASing for coccolithophores across the South Atlantic Subtropical Gyre! https://www.chase-dust.com/blog-bastidor/new-paper-exploring-the-impacts-of-climate-change-on-phytoplankton-bloom-dynamics-in-the-west-antarctic-peninsula monthly 0.5 2024-08-15 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/93702540-e657-48eb-9ff3-573fb2eeae58/Screenshot+2024-08-15+at+14.22.07.png Blog - bastidor - New paper exploring the impacts of climate change on phytoplankton bloom dynamics in the West Antarctic Peninsula - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/51f67ada-bfae-43f0-9971-b43dd392ea9d/Screenshot+2024-08-15+at+14.23.11.png Blog - bastidor - New paper exploring the impacts of climate change on phytoplankton bloom dynamics in the West Antarctic Peninsula - Make it stand out Phytoplankton biomass distribution in the Antarctic Peninsula.

Despite its very low export productivity at out sediment trap site, and contributing less than 2% of the coccolith assemblages in all size fractions, this abnormally Sr-rich species produced disproportionally high percentages of carbonate both in the original trap samples and in the coccolith size fractions due to its large dimension (Guerreiro et al., 2021), resulting in unusually high Sr/Ca ratios. This is in line with previous studies which have also reported S. apsteinii to have unusually high, and still poorly understood, coccolith Sr/Ca ratios (Hermoso et al., 2017; Meyer et al., 2020). https://www.chase-dust.com/blog-bastidor/our-research-topic-at-frontiers-in-marine-science-has-its-first-accepted-manuscript monthly 0.5 2024-01-04 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/c938dbcb-564c-4177-9e89-a671a116a3fe/fmars-10-1308689-g002.jpg Blog - bastidor - Our Research Topic at Frontiers in Marine Science has its first accepted manuscript!

The unique 300 m resolution of the ESA MERIS and ESA/Copernicus Sentinel 3 OLCI instruments give an view of the distribution of Chl-a and offer the unprecedented potential to estimate NPP within the main Galician rias and on the adjacent continental shelf. To our knowledge satellite derived estimation of NPP has never been attempted at this resolution. PRIMUS will contribute to fill this gap by generating and validating a “4DAtlantic Experimental Dataset” of EO-based Atlantic EBUS data, based on recent data from Sentinel-3. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/8f1202bf-3fe8-4de7-9374-564b24c6046f/Figure_map_annual_mean_pp_occciv4-1_1998-2018_area_primus.png Blog - bastidor - PRIMUS: a new ESA-project affiliated to CHASE! - Make it stand out This is a map of the global annual primary production (PP) based on mean photosynthesis versus irradiance (P-I) parameters, for the period of 1998-2018 (image: Kulk et al., 2020). https://www.chase-dust.com/blog-bastidor/85kcd69y58rnlxvrl0q62vu9ue7hnt monthly 0.5 2021-12-15 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/0556637c-7037-4d06-bc2e-803022ced082/MARUM-MSM104-web.jpg Blog - bastidor - “Hot” dusty news from the tropical NE Atlantic! - Make it stand out RV Maria S.

Well, coccolithophores influence and interact with the marine carbon cycle in three main ways. First, being primary producers, they act as sinks of atmospheric CO2 while doing photosynthesis to produce particulate organic carbon (POC). Second, they also act as sources of CO2 while doing calcification to produce particulate inorganic carbon (PIC). Thirdly, they also act as dense mineral ballast to facilitate the transport of carbon-enriched organic material from the surface down to the deep ocean and thereby, improving its chances to get sequestered in the deep ocean. In others words, coccolithophores actively contribute to the functioning of the “biological carbon pump”, through which CO2 is reduced from the atmosphere, but also of the “carbonate counter-pump”, through which CO2 is released back to the atmosphere. To this biogenic PIC/POC ratio we call the rain ratio, and this is largely what mediates the flux of CO2 between the ocean and the overlying atmosphere. The higher is the PIC/POC ratio, the weaker will be the capacity of the “biological carbon pump” to capture CO2 from the atmosphere and to sequester it down to the deep ocean. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1624297206614-NTZWBK2VND5M3NUVYRZY/Figure+6_Guerreiro+et+al.jpg Blog - bastidor - New paper: Carbonate fluxes by coccolithophore species between NW Africa and the Caribbean! - Make it stand out Here, you can see the spatiotemporal variation of (a) UPZspp/LPZspp ratio (light green) in coccolith fluxes of E. huxleyi and G. oceanica typical of the upper photic zone (UPZ), and F. profunda and G. flabellatus typical of the lower photic zone (LPZ) (used as a proxy for nutricline depth dynamics; Guerreiro et al. 2017, Guerreiro et al., 2019), and surface chlorophyll a concentrations (Chl a, black line); (b) total fluxes of POC (green) and bSiO2/CaCO3 molar ratio (orange line) as a proxy for the ratio of silicifying to calcifying plankton [1], (c) rain ratio (CaCO3/POC, in blue) and Coccolith-CaCO3/POC molar ratios (black line); (d) relative contribution of coccolith-CaCO3 to total CaCO3 fluxes by the most important carbonate producing coccolith taxa; (e) total coccolith-CaCO3 fluxes (blue) and surface ocean concentrations of particulate inorganic carbon (PIC) (black line); and (f) fluxes of (from bottom to the top) CaCO3, organic matter, biogenic silica, and lithogenic dust (M1, M2, and M4 data from Korte et al. 2017 and van der Does et al. 2020). https://www.chase-dust.com/blog-bastidor/check-our-latest-dusty-findings-this-friday-30th-april-in-virtual-egu-2021 monthly 0.5 2021-04-29 https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1619689935222-5ZP1XVEG8FZLBPLXDRC1/Screenshot+2021-04-29+at+10.43.29.png Blog - bastidor - Check our latest dusty findings this Friday, 30th April, in virtual EGU 2021!

This is our solution S1 (pH 2), containing Milli-Q water, H2SO4, HNO3 and Saharan dust, which was produced to mimic chemical cloud-precessing of atmospheric dust during its transport by the trade winds from the Sahara desert over the North Atlantic. The Saharan dust was leached in this acid solution for 24 hours in a magnetic stirrer before adding the Milli-Q water for mimicking rainwater (S2 – “step d”). This timespan was chosen according to protocols from previous cloud processing experiments (Spokes et al., 1994; Shi et al., 2009), while the agitation provided by the magnets is to ensure the complete homogenization of the solution. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761027168-PXY3HBBWO8IQCLHGVSHX/b8c3c6a5-f74b-4a59-bf7f-84a6401febe4.jpg Blog - bastidor - News from our dust-fertilisation experiment!

Together with the material collected during AMT29 (boreal fall of 2019), we will have a 2-yr multi-proxy data set for exploring links between atmospheric dust deposition and coccolithophore production across the Atlantic Ocean. https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088831-IRK2DY04N76M8R1W4OEJ/DSC_0863.jpg Aims - Dustco Aims CTD rosette https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088835-JIWQZCY9RHOJYKDYPDNL/DSC_0862.jpg Aims - Dustco Aims CTD rosette https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088857-HAYV0KZRIW9W5WTC7S8D/DSC_0859.jpg Aims - Dustco Aims CTD rosette https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088839-EESWUOT0HWQRJVNIPY8D/DSC_0131.jpg Aims - Dustco Aims NISKIN bottles https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088842-TKBDLZC1WRAQI8I790CT/DSC_0225.jpg Aims - Dustco Aims plankton water samples https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088853-9II7FO04BXWNH638GV8O/DSC_0190.jpg Aims - Dustco Aims Filtering set https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088846-DPE2H57IXXIFEB8YJV9R/DSC_0239.jpg Aims - Dustco Aims Filtering plankton samples https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609761088850-ZUCIXYTU87F240ZPHJ47/DSC_0240.jpg Aims - Dustco Aims Filters https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609783706749-6N7NDGGI48M0YGVBKDDR/Andreia%2B1.jpg Aims Here, Andreia Tracana is working on the wet lab of the ship during AMT29. She is filtering the same water samples that she brought from the Niskin bottles. Each resulting filter will be further analysed at the microscope for the taxonomic identification of the coccolithophore communities (Photo credit: Carolina Sá). https://images.squarespace-cdn.com/content/v1/5ff300efceaa345b8ff2d01f/1609784075961-V2P2AMG3PNQLSJMD2OAH/dust+AMT29.jpg Aims Above, you can see Giulia (left) and Andreia (right) placing a filter inside the dust collector for undertaking underway sampling of atmospheric dust during AMT29. The Anderson high-volume dust collectors was mounted on the deck above the bridge of the ship, containing a motor which sucks air through an air filter, covered with a rain cover. All cellulose acetate filters were sampling for approximately 24 hours, and are currently being analysed for addressing the particles composition and grain-size distribution, and for the nutrient concentrations.
