Experts from SRUC’s Scottish Marine Stranding Scheme (SMASS) were called upon when 12 whales were stranded on the Wadden Islands off the coast of the Netherlands, Germany and Denmark.
SMASS veterinary specialists, coordinated by Dr Andrew Brownlow, joined
Dutch and Belgian teams, spending several days supporting the Dutch led investigation
into the largest mass stranding ever seen of sperm whales in the eastern North
carried out post-mortems and investigations on most of the stranded animals,
IJsseldijk from the University of Utrecht (Faculty of Veterinary medicine), leading
the investigation of the six animals stranded in Dutch waters.
Commenting on this exceptional event Dr Brownlow said: “This is the first
sperm whale stranding that has been investigated in any detail and pulling
together a team to carry out the post mortems has been a huge logistical
undertaking for IJsseldijk.”
“Experts were called upon from across Europe so we were able to post mortem
five out of six animals within 48 hours. This enabled an unprecedented
amount of detail to be gained which, in turn, helps our understanding of the
processes involved in their demise.
Andrew explained why its important to carry out post mortems quickly: “Sperm
whale are perhaps the most difficult of all marine species to examine, given
their size, tough, fibrous blubber and the short time before they start to
decompose meaning you actually run the risk of exploding the carcase. Each
animal probably weighed about 20,000kg and this requires heavy lifting
machinery to even begin to examine the internal organs.”
A proper investigation of this number of animals required significant
experienced manpower deployed very quickly which was the reason SMASS were
asked to help.
The final results are pending and will be released in time, however researchers
have already been able to rule out many potential causes for the stranding. The
animals were in good body condition but in the process of stranding became crushed
under their own weight, which sadly led to their death. Samples were taken for analyses
of their diet, life history and contaminant burden which will also helps
understanding of what may have happened to these whales.
For Andrew Brownlow the period proved particularly busy as, following the
North Sea incident, he was contacted by a range of media outlets seeking his view
on most recent strandings on the Lincolnshire coast.
