Weaving – porcelain 'spines' and bull kelp ‘ecosystem tipping’

Southern ice porcelain and bull kelp (Durvillaea potatorum)

My fragile weaving of porcelain urchin ‘spines’ and kelp intertwines two species, Bull kelp (Durvillaea potatorum) and the long spined sea urchin (Centrostephanus rodgersii). As a result of climate change, this urchin has been carried to Tasmania in the warmer East Australian Current which displaces the nutrient rich cool waters of the Southern Ocean. Many east coast seaweeds have declined due to ecological change from urchin barrens, temperature and nutrient stresses. Degraded marine ecosystems show small markers before ‘tipping’ into collapse.

This work explores fragility, interconnectivity and resilience; a probing of Tasmania’s astonishing temperate marine environment’s ability to survive change.
