Abstract

This dataset presents 35 years of particle flux measurements from Hawaii Ocean Time-Series (HOT) cruises during December 1988 to December 2023 at Station ALOHA in the Pacific Ocean north of Hawaii. Particle flux was measured at a standard reference depth using multiple cylindrical particle interceptor traps deployed on a free-floating array for approximately 60 hours during each cruise. Sediment trap design and collection methods are described in Winn et al. (1991). Passively sinking particulate...

Monthly measurements of particle flux were collected at Station ALOHA as part of the HOT program. Passively sinking particulate matter is intercepted using a free-floating sediment trap array. After screening the collected materials to remove zooplankton and micronekton carcasses, portions of the remaining sample are analyzed for C, N, P and biogenic-Si flux.
