The experiment took place at the Aquarium finisterrae (A Coruña, Spain) between 2022-05-06 and 2023-02-24. Treatment values for each parameter (current in situ vs. climate change) were: 12 °C and 15 °C (temperature); ~7.99 and 7.69 (pH); ~8.63 mg/L and 6.45 mg/L (dissolved oxygen concentration). A total of eight treatments (with 3 replicates each, 5 L aquaria) were set up. Concentrations of dissolved nitrates, nitrite, silicate and phosphate were analysed from each experimental aquaria after one, six and nine months. Inorganic nutrient concentrations in seawater were determined using a SFA (Segmented Flow Autoanalyzer) (Aminot & Kérouel, 2007) with a SEAL Analytical QuAAtro analyzer using established colorimetric methods (Hydes et al. 2010 & Becker et al. 2020). RMNs (Reference Material for nutrients in seawater) with different concentration ranges were used for quality control and accuracy of our analysis. Low nutrient seawater (surface seawater filtered and aged) is also used to control low nutrient concentrations., Horizon 2020 (H2020), grant/award no. 818123: Integrated Assessment of Atlantic Marine Ecosystems in Space and Time, Peer reviewed

A total of eight treatments (with 3 replicates each, 5 L aquaria) were set up. Measurements for pH and total alkalinity (TA) were performed on seawater samples from all the experimental aquaria every 1 – 2 months. Samples for pH were directly collected on cylindrical 10 cm cuvettes and analysed on daily basis. After being thermostated at 25ºC, samples were measured using a manual spectrophotometrical procedure with a Sigma Aldrich impure indicator (Clayton and Byrne, 1993). TA was measured following the double end point potentiometric technique by Pérez and Fraga (1987a) and Pérez et al. (2000). Measurements of Certified Reference Material (Dickson's lab, SIO) were performed in order to control the accuracy of the TA measurements. The uncertainty of TA and pH is about 3 μmol/kg and 0.005 pH units, respectively. In situ additional CO2 system variables were calculated using the R package seacarb (Gattuso et al. 2023) using in situ temperature, salinity, measured pH and TA, the dissociation constants of carbonic acid in seawater (K1 and K2) by Lueker et al. (2000), the equilibrium constant of hydrogen fluoride by Perez and Fraga (1987b), the concentration of total boron by Uppström (1974) formulation, and the stability constant of hydrogen sulphate by Dickson (1990). Mean values for the concentration of silicate and phosphate on the aquaria experiments were used in the CO2 calculations, respectively, mean (and standard) deviations as 2.1 (0.4) and 0.31 (0.03) μmol/kg., Horizon 2020 (H2020), grant/award no. 818123: Integrated Assessment of Atlantic Marine Ecosystems in Space and Time, Peer reviewed

Measurements were performed every month from different parts of the aquaria setup: the input seawater, the reservoir tank (after the filtration of seawater to 5 µm and before the UV lamp) and every experimental aquaria., Horizon 2020 (H2020), grant/award no. 818123: Integrated Assessment of Atlantic Marine Ecosystems in Space and Time., Peer reviewed

A total of eight treatments (with 3 replicates each, 5 L aquaria) were set up. Raspberry-based controllers were set to modify and monitor the water temperature, pH and dissolved oxygen in every treatment. Values for temperature (ºC), pH (NBS scale) and oxygen (% air saturation) were registered every 15 minutes in a database. The parameters were measured using PT100 temperature sensors, and Atlas Scientific Lab Grade pH and Dissolved Oxygen sensors. Every set of sensors was placed on each header tank, corresponding to each treatment (8 in total). Parameter setpoint values for each header tank were finely adjusted on the controller to ensure the treatment target values on each experimental aquaria. Oxygen sensors from treatments with ambient oxygen (~8.63 mg/L) were removed from the system due to calibration issues. Here, an example of the results for temperature, pH and oxygen for every header tank over 24 hours on 31st of December 2022 is presented.

Based on these data, annual main phytoplankton bloom was identified using an adaptive threshold method (see Racault et al., 2012; Ferreira et al., 2021), which involved the following criteria: (i) a 3-week centered running mean of L4 chlorophyll-a must exceed a threshold of 5% above the annual median chlorophyll-a concentration, (ii) for at least 15 consecutive days, and (iii) with data gaps of fewer than 3 days. The phenological metrics included in this dataset were used to characterize both the main bloom and phytoplankton seasonality (see details in Fernández-Barba et al., 2025). Furthermore, to explore causal relationships between phytoplankton phenology and physical variables indicative of climate variability (i.e., marine heatwaves and high-speed wind events), Empirical Dynamic Modeling (EDM)—a cutting-edge approach grounded in Takens’ theorem (Takens, 1981)—was applied. Specifically, the Convergent Cross Mapping (CCM) method, as defined by Sugihara et al. (2012), was employed. In addition, spatiotemporal coherence was assessed using Geographical CCM (GCCM), as developed by Gao et al. (2023)., This repository contains the complete dataset and computational workflows supporting the study on climate-driven shifts in phytoplankton bloom phenology across Spanish marine ecoregions. It includes derived phenological metrics (i.e., bloom maximum, amplitude, initiation, termination, peak timing, frequency, duration, cumulative chlorophyll-a, and seasonal cycle reproducibility) based on 26 years of Copernicus L4 chlorophyll-a multi-satellite observations at 1 km horizontal resolution. Additionally, it hosts the outputs of spatiotemporal causality analyses through (Geographical) Convergent Cross Mapping, which identify nonlinear interactions between phyotplankton bloom dynamics and climate extremes such as marine heatwaves and high-speed wind events. The repository provides fully reproducible code for data preprocessing, phenological indices extraction, causal inference modeling, and figure representation for both the main manuscript and supplementary materials. These resources enable deeper exploration of the mechanistic links between climate variability and ecosystem responses in coastal marine systems. This work facilitates future research on ecological forecasting under transient climatic perturbations and contributes to the understanding of regional-scale biophysical coupling in the ocean., This research was funded by the European Union –NextGeneration EU– as part of the MITECO program for the Spanish Recovery, Transformation and Resilience Plan (Recovery and Resilience Facility of the European Union established by the Regulation (EU) 2020/2094), and was entrusted to CSIC, AZTI, SOCIB, and the universities of Vigo and Cadiz., Peer reviewed
