A large bloom of Salpa spp. in the northeastern Pacific during the spring of 2012 resulted in a major deposition of tunics and fecal pellets on the seafloor at ∼ 4000 m depth (Sta. M) over a period of 6 months. Continuous monitoring of this food pulse was recorded using autonomous instruments: sequencing sediment traps, a time‐lapse camera on the seafloor, and a bottom‐transiting vehicle measuring sediment community oxygen con...

Sinking particulate material collected in sequencing sediment traps moored at 3500 m depth (600 m above bottom) from 1993 to 2008 at the abyssal time‐series Sta. M in the northeast Pacific was analyzed via microscopy and digital imaging. Intact zooplankton fecal pellets were quantified and size, shape, and carbon content were measured. The most common identifiable fecal pellets were from larvaceans, which feed on small particl...

An 8‐yr time‐series study of the trophic coupling between a pelagic food supply and its utilization by the sediment community was conducted at 4,100‐m depth in the eastern North Pacific between 1989 and 1998. Supply of sinking particulate organic carbon (POC) and particulate total nitrogen (PTN) was estimated from collections made with sediment traps moored at 3,500‐ and 4,050‐m depth (600 and 50 m above bottom). Sediment comm...
