... Each component is complementary while simultaneously representing different processes of market squid dynamics: (1) recruitment preceding the survey; (2) suitability of habitat allowing a squid to occupy a location; and (3) localized aggregation behaviour that modulates haul-specific catch observations. An advantage of the three-step approach is that model output for each step may have utility for different comparisons, including population-scale dynamics (recruitment), predicted shifts in habitat occupancy (presence/absence), and local catchability (haul-specific abundance; Suca et al., 2021). The stratum-specific recruitment model serves to identify the drivers of overall abundance of market squid in a survey stratum linked to interannual variability in spawning and paralarval and juvenile growth/survival conditions leading up to and during the sur- vey. ...

... When spawning locations (i.e., 'sources') are known, particles can be tracked forwards-in-time, providing estimates of settlement magnitude that can be related to observed settlement and recruitment or patterns in fisheries productivity (Everett et al., 2017;Schilling et al., 2020). Conversely, when spawning locations are unknown (or poorly defined), particles can be tracked backwards-in-time from known settlement locations (i.e., 'sinks'), providing estimates of putative spawning locations and recruitment origins (Hernández et al., 2022;Putman & Naro-Maciel, 2013;Torrado et al., 2021). ...

... research efforts in recent years, which have focused on sand lance from the southern Gulf of Maine (e.g. Stellwagen Bank), Cape Cod, and Nantucket Shoals (Silva et al., 2020;Suca et al., 2021;Baumann et al., 2022;Suca et al., 2022). What remains unresolved, but has clear conservation implications, is the genetic structure and population connectivity of A. dubius across its entire geographic distribution on the NWA. ...

... This spatial pattern also applies to hake's larval distribution. While in late winter hake larvae were distributed alongshore over the study area (Rodríguez et al., 2015b), larvae were more concentrated within the boundaries of an anticyclonic eddy in summer (García-Fernández et al., 2021). ...

... Formal education systems involve curriculum-based learning in education and research institutions (e.g., universities), which house most ECOPs at some point in their career, with many programs being highly specialized within a single field. Today, there is growing demand for interdisciplinary training [54], where ECOPs work across cognate fields within and across social and natural science realms [59][60][61]. It also involves collaborating and exchanging knowledge across policy, science, and practitioner divides [62]. ...

... Jiang et al. (2022) have proposed to construct a movable laboratory that includes a mothership and several full-ocean-depth autonomous and remotely operated vehicles to obtain samples in the hadal trenches. Yoerger et al. (2021) have developed an AUV to address the specific unmet needs for observing and sampling a variety of phenomena in the ocean, including environment and biodiversity. However, the abovementioned devices are driven by underwater screw propellers, which will severely disturb the water body and sediment. ...

... The amplified DNA fragments are sequenced and then assigned to species or taxa using available genetic databases (e.g., European Nucleotide Archive (ENA); Taberlet et al., 2012). eDNA metabarcoding has high potential to study and reveal deep-sea biodiversity since it overcomes most difficulties inherent to classical methods (Brandt et al., 2021;Govindarajan et al., 2021;McClenaghan et al., 2020). For example, Visser et al. (2021) described deep-sea cephalopod communities along the water column (between 50 and 1600 m depth) around Terceira Island using eDNA metabarcoding. ...

... It has been reported that these species have evolved several adaptations for living in a low-oxygen environment, including reduced metabolic rates and enhanced gas exchange mechanisms (Childress & Seibel, 1998). Low basal metabolic rates are probably related to non-visual hunting (Childress &Thuesen, 1992), as occurs in C. braueri (Badcock & Merrett, 1976 (Palma, 1990;Valls et al., 2014;Bernal et al., 2015;Olivar et al., 2019), implying lower mobility requirements, which would result in higher energy reserves (Caiger et al., 2021). ...

... Their exceptional nutritional quality and high local abundance sustain commercial fish stocks (e.g. cod, tuna) and often promote spatial aggregations of iconic piscivores such as sharks, seabirds, and marine mammals (Engelhard et al., 2014;Silva et al., 2020). Some sand lance species are targeted commercially for oil and meal (Lynam et al., 2013), as for example in the North Sea, where peak landings of >1 million tons annually (van Deurs et al., 2009;ICES, 2010) caused declines of seabird and marine mammal populations in the late 1990s (Furness, 1999;Furness and Tasker, 2000;Daunt et al., 2008). ...
