(A) Schematic of samples collected for this work at 5 sites (0–4) representing three habitat types (seawater, intra-field, and diffuse flow) using two sampling methods (Niskin and Deep Environmental Sample Processor ESP). (B) ESP deployed at sites 1 and 4 showing position of samples collected at Site 1 with Niskin and ESP. (C) ESP sampling wand deployed at Site 4 showing positions of samples collected with Niskin and ESP. (D) Site 2 Niskin samples being collected showing position of intra-field and diffuse samples collected at Site 2.
