<div><p>Samples for nutrient measurements (nitrate (NO3<sup>-</sup>), nitrite (NO2<sup>-</sup>), ammonium (NH4<sup>+</sup>), phosphate (PO4<sup>3 -</sup>) and silicate (SiO4<sup>4 -</sup>)) and ammonia oxidation rates were collected using a conductivity, temperature, depth (CTD) rosette (Sea-Bird Electronics) equipped with 12 10 L Niskin bottles. Dissolved oxygen (O2) concentrations were measured with a CTD sensor package (SBE-43; Sea-Bird Electronics) on the Hoodsport ORCA buoy mooring and were calibrated against Winkler O2 determinations for all but the CB974 cruise. Ammonium and nitrite concentrations were measured within 2 h of sample collection onboard using the o-phthaldialdehyde (OPA) fluorescence method and spectrophotometrically, respectively.

Hood Canal - nutrients
<div><p>Samples for NO3, PO4, and SiO4 were filtered with a 0.22 um size pore filter and frozen at -20 °C for shore-based analysis at the University of Washington. Those analyses were performed at the Marine Chemistry Laboratory of the School of Oceanography using a Technicon AutoAnalyzer II (UNESCO, 1994).</p></div>
