“…The other contaminant of particular concern is TBT, which has consistently been recorded in sediments and biota across Astrolabe Reef (Ross et al 2016b). TBT is a potent and persistent toxin, considered to be one of the most effective marine anti-foulants ever used (Evans 1999;Sousa et al 2014).…”

“…Analyses of trace metals, PAHs and organotins in sediments, the water column and in biota have indicated significant but localised contamination (Ross et al 2016b;Dempsey et al 2016). More than 3 years after the grounding, Rena-derived PAHs, copper, tin and zinc are present in reef sediments above Australia and New Zealand Environment and Conservation Council (ANZECC) guideline concentrations.…”

“…Copper and other metals (iron, aluminium, zinc and manganese) are also present in the water column overlying the debris field at concentrations that are elevated relative to reference locations (Dempsey et al 2016). Of continuing concern is the presence of tributyltin (TBT), a constituent of anti-fouling paint banned in 2008 (IMO 2001), in sediments over much of Astrolabe Reef and in biota across several trophic levels (Ross et al 2016b). Body burdens of TBT lower than those recorded in Astrolabe Reef biota are known to have caused adverse physiological effects in organisms elsewhere (Evans 1999;Sousa et al 2014).…”

“…Despite the Rena having been certified as TBT free, TBT-based anti-fouling several layers beneath the Rena's most recent coat of paint was scraped from the hull during the initial grounding, through subsequent wreck movements and, to a lesser extent, by the act of salvaging the hull. TBT is present in sediments on and adjacent to Astrolabe Reef at concentrations likely to have adverse effects (Ross et al 2016b). It is also present in biota including whelks, urchins and fishes.…”

The sinking of the MV Rena on Astrolabe Reef (Otaiti) in the Bay of Plenty, New Zealand, resulted in the release of oil and ship debris, including dangerous goods carried as cargo. Two key questions of concern to the public and environmental managers were posed immediately: what was the impact of the Rena oil spill and how long would it take for the marine environment to recover? The research that began immediately after the ship grounded provided answers, as documented in this special issue.

ContextSeabirds were the most common taxa captured alive as part of the oiled wildlife response to the grounding of the container vessel MV Rena in the Bay of Plenty, New Zealand. AimsTo describe the management of seabirds during the spill response, to outline the common problems encountered and to make recommendations for future responses. MethodsSeabirds were collected from 7 October 2011 to 14 January 2012. They were stabilised and underwent pretreatment, washing and rinsing procedures to remove oil, followed by swimming physiotherapy to restore waterproofing and long-term housing in outdoor aviaries. The birds were released in batches close to the original sites of capture once the wild habitat was cleaned. Key results428 live seabirds were admitted. There were two temporal peaks in admissions associated with the ship grounding and when the ship broke up. The majority of live birds were little penguins (Eudyptula minor; 394/428, 92%). Most seabirds admitted (393/428, 91.8%) were contaminated with heavy fuel oil, with the remainder (35/428, 8.2%) found unoiled but starving and/or exhausted or with injuries. Little penguins had lower mortality during rehabilitation (28/394, 7.1%) than other seabird species combined (27/34, 79.4%). Seabirds in poorer body condition on arrival had higher mortality, and unoiled birds were also more likely to die than oiled birds. In oiled little penguins, the degree of oiling on the plumage ranged from 1 to 100%, but mortality was not significantly associated with the degree of oiling (P=0.887). Pododermatitis affected 66% of little penguins. The most common causes of death (n=45) included weakness, anaemia and hypothermia in oiled seabirds (16/45, 35.6%), and starvation and weakness in unoiled seabirds (14/45, 31.1%). ConclusionsTotal survival to release was 87.1%, primarily influenced by the species involved and the body condition of the birds on arrival. Unoiled seabirds had higher mortality rates than oiled seabirds. ImplicationsOiled wildlife can be rehabilitated with good success, even when heavily oiled, or to a lesser extent, when found in poor body condition. More work is needed to refine species-specific rehabilitation protocols for seabirds, especially for those being admitted in emaciated body condition.
