©2020 Biological and Chemical Oceanography Data Management Office.A benthic lander is an autonomous research platform used in marine research to take measurements directly on the seafloor. Benthic landers are carrier systems to which different measuring and sampling devices can be attached. They transport these devices to the seafloor and back up again. Autonomous means that the lander is not connected to the ship via a cable. It can thus work independently on the seafloor for a long period of time.

| Benthic fluxes collected in August 2018 and July 2019 in northern Gulf of Mexico shelf on R/V Pelican | A custom benthic lander system was deployed at each of the stations to carry out in situ flux measurements for total oxygen utilization (TOU). | custom benthic lander system |
| Benthic iron data on the Oregon Shelf from samples collected on R/V Oceanus cruise OC2107A during July to August 2021 | Refer to Knoery, et al. (2019) for a description of the benthic lander nicknamed "SUSANE", which stands for "System for Underwater SAmpling of beNthic Environments". In short, this sampler was designed to simultaneously collect 16 discrete water column samples at a centimeter-scale vertical resolution. The small device (40 × 40 × 60 cm) is deployed from a small boat using a cable or a Scuba diver. The device can contribute to the characterization of vertical concentration gradients in benthic water columns. | SUSANE |
| Benthic chamber geochemical data obtained with an in situ benthic lander from the R/V Savannah at sampling stations across the Louisiana shelf and slope in the Northern Gulf of Mexico during four cruise between July 2021 and July 2022 | Benthic chamber samples were collected with a benthic lander and sampling racks designed and fabricated at Georgia Tech. Electronic equipment controlling the autonomous benthic lander sample collection was designed and developed by Analytical Instrument Systems, Inc. in collaboration with the Georgia Tech group. The shelf lander included a SBEST Seabird pump to mix the overlying waters, whereas the deep-sea lander carried a mechanical stirrer designed and fabricated by Georgia Tech. | benthic lander |
