  abstract = {{L}andscape ecology is a key discipline for studying the relationships between spatial patterns and ecological processes, as well as for monitoring macro-scale changes in ecosystems. {U}nlike terrestrial landscapes, which have been extensively studied, the open-ocean pelagic environment presents unique complexities that require innovative approaches for its understanding. {A}ggregations of micronektonic and macrozooplanktonic organisms in layers are prominent features of the open-ocean pelagic zone. {S}uch visually cryptic features can be revealed by echosounders as pelagic {S}ound {S}cattering {L}ayers ({SSL}s). {W}e characterise various pelagic seascapes and their relationships with environmental parameters across three oceanographically contrasting tropical regions, characterised by diverse ecological patterns, using an integrated methodological framework that combines dual-frequency acoustic analysis (18 and 38 k{H}z). {D}iel vertical migration is a common feature that involves epipelagic and mesopelagic {SSL}s. {N}evertheless, there are significant regional contrasts in {SSL} spatial distribution as oceanographic features influence {SSL} patterns and micronektonic acoustic backscatter. {A}coustically defined pelagic seascapes reveal biological-physical coupling and {SSL} responses to oceanographic variability at meso- and macro-scales. {SSL} distribution was significantly driven by oceanographic variables such as temperature, chlorophyll a, salinity, oxygen, and {PAR}, as well as by mesoscale eddies that structured their spatial patterns, with anticyclonic eddies concentrating {SSL}s' acoustic backscatter at their centres and cyclonic eddies exhibiting scattered acoustic backscatter at their peripheries. {T}his framework enhances our ability to assess how climate variability and changing ocean conditions influence open-ocean pelagic ecosystems. {D}eveloped and demonstrated at a broad regional scale, this validated approach establishes a transferable framework for characterising pelagic habitats through integrated {SSL} structures, enabling its application across wider spatial and temporal domains to advance understanding of global biophysical and ecosystem dynamics.},
