South Walney SealCam
This stream was installed by Andrew Deakin (Octopus) and Sarah Dalrymple (CWT) on 7 April 2017. It uses a Raspberry Pi streambox with Cirrus Logic audiocard, running V 3.1 of the streambox software developed by Stef Cousot at Locus sonus and others. It includes the live audio streaming software Darkice, an open source project by Ákos Maróy and Rafael Diniz.
The streambox was built by Grant Smith (soundCamp). It uses a Teltonika RUT950 4G router with an external antenna on a mast, to connect to an ee mobile tower. The design is based on a nucleus for bees or a small vernacular building, with an overhanging slate roof providing mass and weather protection for the microphones. It recalls the Greek root: oikos in ecology, meaning house.
The streambox is located on a shingle beach at the Southernmost tip of S Walney Island, facing the Atlantic ocean across the bay from Barrow-in_Furness. The beach supports a distinctive flora including the rare Walney Geranium (G. sanguineum var. striatum). In Autumn, seals come to the beach to give birth. From mid April it is home to a large colony of gulls. Sandwich terns, Eiders and other waterfowl and waders can be heard from the water and the beach. The box sits on a small concrete plinth above the tideline.
