  • This Geographic Dataset (GD) contains the geographic locations of the active and historical tide gauge stations operated by the Portuguese Hydrographic Institute, as well as their near-real-time (NRT) sea surface height (SSH) observations. The SSH observations (http://vocab.nerc.ac.uk/collection/P07/current/CF15N1/) are provided in Coordinated Universal Time (UTC, ISO 8601) and are referenced to the Hydrographic Zero (ZH, EPSG:10349). Quality control (QC) flags comply with the vocabulary available at https://vocab.nerc.ac.uk/collection/L20/current/. The processing levels follow an internal convention. Level L1 corresponds to data without quality control (QC). Level L2 corresponds to data that have undergone automatic QC (e.g., range checks, spike detection, and temporal consistency tests). Active tide gauge stations: tide_obs_stations_nrt Available datasets: tide_obs_data_nrt_l1 – Near-real-time (NRT) data without QC (L1), sampled every 10 or 60 seconds, with a latency of 1 minute and a rolling time window of 8 days. tide_obs_data_nrt_l2 – Near-real-time (NRT) data with automatic QC (L2), sampled every 5 minutes, with a latency of 1 day and a rolling time window of 15 days. Historical tide gauge stations: tide_obs_stations_hist To access the complete observation time series, or specific historical periods, a request should be sent to cedencia.dados@hidrografico.pt. This dataset is part of the High-Value Datasets (HVD) identified under Implementing Regulation (EU) 2023/138 of Directive (EU) 2019/1024 on open data and the reuse of public sector information.

  • Within Portugal's National Biological Sampling Project (PNAB) a set of activities are conducted in the collection, management and use of biological data, collected from the registered commercial fleet in mainland Portugal (fisheries-dependent data) and several research surveys (independent fisheries data). These activities allow the assessment of the state of fishery resources, population structure, distribution and abundance of resources, diversity and dynamics of biological communities associated with the fishery resources and biological studies (growth, reproduction).This resource shows the geographic distribution of silvery pout abundancy index (nr. individuals/hour) registered during the CRUSTACEOS2011 campaign in June 2011.

  • Identification and enumeration of harmful and potentially toxic phytoplankton species from water samples collected weekly in shellfish production areas, coastal and transition in mainland Portugal since the year 2014. These analyzes are part of the national system of monitoring bivalve mollusc production areas of IPMA and are considered in the zoning and in making decisions regarding their status. The data is collected for the requirements of Regulation (EC) No 854/2004 of the European Parliament and of the Council of 29 April 2004.
