Last chance for a run commute, gorgeous morning for it and even found a little kekeno down on the waterfront 🌊
View of the horizon at sunrise, the foreground is dark hills in silhouette and the sky is pink and orange. View of a concrete bridge with buildings in the background. Under the bridge there are some large boulders at the edge of the sea. In the middle of the photo there is a small brown fur seal (kekeno) with a shiny wet coat. View across a calm sea with hills on the horizon, there is a small rowing boat in the middle with two people in it. The sun is low in the sky and there are light clouds. A row of colourful blue, white, yellow and red painted boat sheds next to the sea.

Summary schematic diagram of organic carbon (OC) flux and distribution in an idealised submarine canyon-channel-fan turbidite system, similar to the Kaikoura-Hikurangi depositional system. Frequent events (high recurrence interval) allow young terrestrial and marine OC to be flushed laterally into the deep ocean via
submarine canyon(s) without a direct river connection. (A) Interpreted inter-event sediment and OC accumulation, with the submarine canyon acting as a charging capacitor. (B) Intra-canyon mass wasting (due to physical disturbance, e.g., earthquake ground-shaking), with measured intra-event OC lateral flux and partitioning along a fine-grained turbidity current and resulting turbidite deposit shortly following deposition. Schematic cores below the seafloor show idealised Kaikoura event bed (KEB) deposits.
