• Is this a Unusual Mortality Event?– Yes- Average annual beaked whale stranding incidence 4.3.– More cases since August 1st than in the whole of the previous

decade

• Is this due to increased abundance?– Probably not, no increase in sightings data associated with

this event (Seawatch, Shorewatch, HWDT Whale Track)

• Is there an increase in carcase reporting?– Some increase in effort in Scotland.– No unusual on-shore wind profile- but this to be quantified.

• Any evidence for infectious or toxic disease?– Unclear from pathological data, unlikely based on

epidemiological analysis– Strandings incidence not consistent with infectious or toxic

aetiology

• Any evidence for trauma– No evidence for skeletal trauma – Acoustic trauma likely inconclusive due to decomposition

state and lack of necropsy investigation in Ireland

• Exposure to sonar could lead to direct barotrauma, gas bubble emboli, longer dive duration, less foraging behaviour and potentially risk of stranding

• Three distinct regions that have received strandings:• West Ireland• Western Isles• West Scotland

• Some areas with no strandings at all

Initial carcase drift modelling results

Single localised source doesn’t reproduce the geographic spread and relatively short timespan of strandings:

• Insult constrained temporally but not spatially?• Carcass drift properties different?• Wider source area?• Animals dispersed before dying?• Model assumptions wrong?

.

Cluster in the Porcupine Seabight:

Clearly not a fit…

• Mortalities randomly scattered in a a circle

• Most influence ocean currents

• Downwind drift in the 1% to 2% range

9

Larger and more northerly source

Better fit to data

Smaller source region Seems to miss out

strandings in Western Isles

Inverse carcass drift modelling- next steps

• Refine ocean and wind models used – acquire higher resolution AMM15 from the Met Office

• Expedite analysis of acoustic records collected under the COMPASS project (EU INTERREG VA)

• Refine the wind/wave/carcass drift representation• Incorporate estimations of carcass decomposition to improve temporal pattern of

strandings.• Run simulations with varied drift/buoyancy characteristics, detection probability, etc to

generate more probabilistic maps of the source• Incorporate Icelandic strandings?

Ongoing work…Acoustic• Identify other noise sources

• Earthhquakes• Seismic?• Mid range sonar?

• Request sent to UK Ministry of Defence for MOD activity between 01 July to 10th August 2018 in the area of 51o and 57 o N and 10 o and 18 o W

• Other nations’ noise generating activity?Genetic• Preliminary analysis of mtDNA short fragments to identify species and sex• Subsequent analysis using ddRAD may elucidate to kinship relationships

and measures of genetic diversity and population structure.

Health• Screening for morbillivirus by PCR• Screening for POP from blubber samples• Histopathology pending
