This will operate approximately 2-3 m above the seafloor while collecting imagery. This gear does not touch the seafloor under normal operations. While DTIS is the principal gear we intend to use, we will also have on board a beam trawl, epibenthic sled and Van Veen grab. These sampling methods will be used to collect specimens to confirm the identification of taxa seen in the video and still imagery, to support biological and biodiversity studies, or if there is a failure with the DTIS. The gear used for this sampling will depend on the seafloor type; hard or rocky substrate is expected on the seamounts, and an epibenthic sled (1 m wide) will be the main tool used. On occasion on softer sediment a grab (surface area 0.25m2) or beam trawl (4 m width) may be deployed. Towed camera system (no seafloor contact) The NIWA “Deep-Towed-Imaging-System” (DTIS) is a deep- sea camera frame that is towed with the vessel at slow speed (Figure 1). It is kept at a height of 2-3 m above the seafloor September 2015 EPA0374 3 Form 1 – Permitted activities: Pre-activity notice while video and still camera imagery is collected over distances of up to 2 km. It also has a small CTD and other instrumentation attached. It has a positioning beacon and altimeter to help safe operation. This gear will be used to undertake baseline and monitoring surveys of the large animals (>2cm) that live on or just above the seafloor. This gear will not touch the seafloor. Figure 1: The DTIS towed camera system Seamount sled This is small epibenthic sled,1.5 m long, by 1.0 m wide, and has a vertical opening of 0.5 m (Figure 2). It is fitted with a positioning beacon, meaning we can target fauna of interest that we see in camera transects to collect live specimens. It is towed at 1-1.5 knots. It is designed to operate on rough or hard seafloor, and to run over the seabed surface, and not dig in. There may be up to 12 sled tows. Each will be targeted and sample a maximum of 500 m2 of seabed. In total, about 6,000 m2 (0.006 km2) of seafloor may be disturbed. Figure 2: Seamount sled, designed to sample larger organisms living on the seabed. The mouth width is 1 m and mesh size is 25 mm Beam trawl The beam trawl consists of a net attached to a 4 m wide beam that is towed slowly at 1.5 knots for up to 1 km of soft-smooth September 2015 EPA0374 4 Form 1 – Permitted activities: Pre-activity notice seafloor to sample benthic invertebrate fauna and small fish (Figure 3). The beam trawl has a ground-rope with small rubber discs that prevent it digging into the sediment. Allowing for up to 6 deployments, the total area covered would be 24,000 m2 (0.024 km2). Figure 3: Beam trawl, designed to sample larger organisms living on the seabed. The mouth width is 4 m and cod-end mesh size is 25 mm. Van Veen grab This is a small bucket-like grab that takes a sample of the upper few cm of the seabed and covers an area of 0.25m2 (Figure 4). Up to 6 grab samples might be taken if it is felt that biological samples can be collected without having to use larger towed gear which have more impact. The maximum total area would be 1.5m2.

If progress permits, or if bad weather forces a change in the camera-based work, some additional sled sampling/beam trawling/grab sampling may be carried out on fished seamounts of the “Big Chief” complex (south of Andes), Shipley Seamount (north of Graveyard). These are within the coordinates given above and shown as the dashed line in the figure below. Describe the current state of the area and the surrounding environment, including any known sensitive environments: The seamount features of both the Graveyard and Andes seamount complexes have been surveyed by NIWA in the past. The Graveyard comprises 28 small volcanic cones covering an area of about 140 km2 on the northern flank of the Chatham Rise (Clark et al. 2010). Orange roughy aggregate for spawning on several of the features, and they have been commercially fished since the mid-1990s. A number of unfished seamounts have extensive areas of reef-like coral habitat composed of stony corals Solenosmilia variabilis and Madrepora oculata. These offer an open-lattice type structure that is habitat for diverse benthic invertebrate communities, including squat lobsters, seastars, brittle stars, polychaete worms, and crabs (Clark & Rowden 2009).The stony coral communities are recognised as “sensitive habitats”, and are confirmed as extensive on Gothic, Pyre, and Ghoul features in the complex, They occur also in patchy locations on several other features (Clark et al 2010b). Time series of surveys have been carried out (2001, 2006, 2009, 2015) to monitor changes in the benthic fauna on these seamounts following the closure of several in 2001, but to date no recovery of the stony coral reefs has been observed (Williams et al.
