“…As described in Reference [9], the interpolated ADCP currents for horizontal particle tracking were imported into Arcmap and converted to a 3109 m × 3109 m cell size raster for velocity and direction (angle) file. Then, tracking was performed using a particle track tool with 25-m step length until it reached the limit of the current field.…”

“…The particle-tracking algorithm used employs a predictor-corrector scheme of predicting the future location of a particle based on the local velocity field, as interpolated from the nearest raster cell centers [50]. The comparison of tracks with track intervals of 25, 250, and 2500 m (Annex 2 in Reference [9]) proved that the successive locations of the particles were not tied to the interval step.…”

“…While benthic georeferenced diversity is generally used for MPA identification, low interest is given to the pelagic ecosystem, the biggest marine ecosystem, which connects all the others and provides the primary production that feeds the whole marine food web. Structures such as fronts [5,6], canyons [7][8][9][10], and seamounts [11] are described as sites of local fertilization due to the hydrodynamic processes that induce mixing of nutrient-rich water into the upper photic zone. The resulting increase in productivity attracts marine vertebrates such as turtles [12], tuna [13], marine mammals [14,15], and sharks [16].…”

“…The aggregation of top predators, attracted by or growing on the local elevated productivity, is the main driving force for the protection of seamounts [22] and submarine canyons [23]. Additionally, vertical coupling between pelagic and deep-sea benthic ecosystems occurs on short time scales (several days down to 1400 m depth [9,24]), and shallow seamounts and ridges provide a direct link between the photic and deep-sea habitats positively affecting diversity, density, and behavior of benthic and pelagic organisms [25][26][27]. On the other hand, fronts, such as mobile features, are not usually protected, although fronts are the main migration routes of marine vertebrates and are suggested as priority conservation areas [28].…”

The Cape of Gata region (southeast Spain) allocates the thermo-haline Almeria–Oran front (AOF), which separates two biogeographical zones, with a very irregular bathymetry, consisting of two canyons and seamounts in an area of 100 × 100 km. An interdisciplinary oceanographic sampling strategy allowed us to solve mesoscale processes including current–bathymetry interactions. Subsurface fertilizing processes and elevated chlorophyll a concentrations were found at the front, seamount, and submarine canyons, turning an apparently oligotrophic area into a rich one. According to a horizontal tracking simulation, the deep chlorophyll maximum (DCM) at the front is located above the pycnocline and travels fast offshore, transporting productivity from the fertilization process quickly from the region. The DCM at the seamount, in contrast, develops below the pycnocline and remains for almost three weeks in this area. In spite of the coastal marine protected areas (MPAs), a high surface nitrate concentration plume with its origin in a small coastal area without any protection was detected. Local circulation patterns and bathymetry–current interactions provide elevated productivity in surface water which is vertically connected to deep-sea fauna via the daily vertical migration of zooplankton, suggesting elevated biodiversity on the seamount and canyons of the area studied. Based on these results, and considering the presence of coastal MPAs and a Coastal Area Management Program, future studies on benthic fauna, an enlargement of coastal MPAs, and a transboundary land–deep-sea management program are suggested.

Accurate and detailed reporting of methods is essential for scientific progress, yet it is widely accepted that authors across all scientific fields tend to provide insufficient methods detail. Given the recent proliferation of automated and semi‐automated technologies for data collection, to address this widespread issue the details needed for interpretation and reproducibility for each specific technique first need to be identified. A systematic literature review assessed the comprehensiveness of method details reported by 116 peer‐reviewed studies published between 2017 and 2020 using the FlowCam (a widely used imaging flow cytometer) to image phytoplankton, finding all to be lacking in critical details, inhibiting reproducibility, and limiting the veracity of some findings. Through this review and three case studies, we identify several key method details that should be reported by FlowCam studies to ensure their findings are credible, comparable, and replicable and illustrate the wide‐reaching implications for not doing so. Future studies using FlowCam for phytoplankton analyses should ensure clear reporting of all relevant details relating to the FlowCam unit, sample preparation, run settings, post‐processing of images, and the considered use of only verified measurement outputs. A methods reporting template is presented as a guideline intended to enhance the quality, interpretability, and repeatability of future FlowCam papers. The pervasiveness of inadequacies in FlowCam methods reporting identified here highlights how vital it is for users of any automated or semi‐automated scientific technologies to have a clear understanding of the impact of all method details on their findings, and to report these details adequately.
