In September 2022 Ecosystem Sciences Division (ESD) scientists of the Pacific Islands Fisheries Science Center (PIFSC) flew into American Samoa to survey 18 sites along a water quality gradient off of Aua. This specific metadata record refers to the quantitative analysis of benthic foraminifera, benthic microalgae, and macroinvertebrates from samples collected between 9-28 September 2022. Samples were preserved in the field, and brought back to the NOAA Inouye Regional Center (IRC) and analyzed via microscopy. Collection methods for each bioindicator were as follows: (1) Benthic foraminifera: Sediment samples were collected (Sept 26, 2022) using a small sediment corer (60 ml syringe with the tip removed and a stopper placed there instead). Only the top 3 cm were retained. Under the microscope, benthic foraminifera were picked out of the sediment and identified. (2) Benthic microalgae: Microscope slides were deployed (Sept 11-26, 2022) on the seafloor at each site for 2 to 3 weeks and the benthic microalgae that settled will be fixed and preserved in Lugol's solution and analyzed. Microalgae included diatoms (pennate and centric), dinoflagellates, chlorophyta, and cyanobacteria. (3) Macroinvertebrates: Plastic scouring pads were deployed (Sept 11-26, 2022) and attached to the substratum via zip-ties for 2 to 3 weeks. The scouring pads were removed after the settlement period, all plastic zip-ties and additional waste were removed from the reef. Macroinvertebrates that settled on the scouring pad were placed into sampling jars and fixed and preserved with 4% formalin, and subsequently analyzed under the microscope. Land-based sources of pollution negatively impact reef communities. Our goal here was to identify non-coral bioindicators for poor water quality. Benthic foraminifera, benthic microalgae, and macrinvertebrates are all know to respond to poor water quality. We set out to assess the impact of poor water quality on non-coral reef communities in Aua.

This mission (Project number 31303) sought out to examine the impacts of LBSP on reef communities (coral and non-coral) in Aua, a high priority watershed in American Samoa. This mission builds on prior assessment and monitoring surveys of benthic reef communities conducted in Faga'alu and Vatia bays in 2012, 2015, and 2022 to address National and Jurisdictional goals to reduce the impacts of LBSP in local priority watersheds. Together with periodic monitoring, this coral reef community baseline for Aua reef will allow scientists to quantify temporal changes in the condition and integrity and enable Jurisdictional and Federal resource managers to make informed decisions pertaining to the protection and preservation of critical habitats. The overall effort required to evaluate the effectiveness of management strategies is significant and requires close coordination between local and Federal efforts.
