# A new study published in the Communications Earth and Environment has revealed major gaps in global ocean biodiversity data. Analysing 19-million records, researchers found systemic imbalances that risk skewing ecological interpretations and conservation strategies. The geographic distribution of data was heavily skewed towards the Northern Hemisphere, accounting for over 75-percent of the records analysed. Researchers say inaccurate or incomplete biodiversity data risks misinforming management strategies, leaving key species and habitats vulnerable, especially in the face of accelerating ocean changes.
