Abstract
To manage and protect marine ecosystems, we first need a spatialised knowledge of the seascape-scale processes surrounding them. However, we lack spatially explicit understanding of how regional processes influence biological patterns in many marine systems. This is especially true of remote marine ecosystems, such as those in the deep sea. Here, we conceptualise potential seascape-scale environmental influences on deep-sea hydrothermal vent ecosystems, guided by experts and literature. We propose environmental characteristics that may shape local biodiversity patterns, such as community structure, habitat availability, and temporal stability. Next, we develop pipelines from data extraction to analysis to improve spatial data accessibility and investigate which variables can be used to draw similarities among vent fields. Finally, we group vents from different regions according to shared environmental characteristics. We show that vents that are spatially isolated and have different species pools can share similar environmental characteristics across ocean basins, including geological, oceanographic, and biological dynamics. We thus illustrate how large-scale environmental data can be used to compare seascape attributes across remote, island-like vent ecosystems. We suggest that looking beyond local scales to consider how seascapes both influence and distinguish different vent systems within a global setting is important for conservation and macroecological contexts.

Data availability
The data used in this manuscript were openly available for download, as described and cited in the methods and Supplementary Materials. The processed data are available from https://doi.org/10.6084/m9.figshare.31558687. We also provide a list of data sources, so others can access and use these for their ecosystems of interest. We provide the R code used to generate the results presented in this study at https://github.com/abbiesachapman/vent_seascapes. We link our extracted data (via vent-field identifiers) to the InterRidge Vents Database (https://doi.org/10.1594/PANGAEA.917894), to ensure the data are user-friendly and can be used in conjunction with this resource.
