Dear List members,
My co-authors and I are happy to share our new manuscript: "Seasonal and
diel acoustic presence of North Atlantic minke whales in the North Sea",
published in Scientific Reports.

Risch, Denise, Samuel C. Wilson, Mathilde Hoogerwerf, Nienke CF van Geel,
Ewan WJ Edwards, and Kate L. Brookes. "Seasonal and diel acoustic presence
of North Atlantic minke whales in the North Sea." *Scientific Reports* 9,
no. 1 (2019): 3571.

Despite frequent records from other parts of the North Atlantic, minke
whales have never been
acoustically recorded in the North Sea. This study investigated the
detectability of pulse trains
previously associated with this species in other regions, in acoustic data
from ten sites along the east coast of Scotland. Since preliminary results
confirmed pulse train presence, subsequently, an automated detector was
applied to these data to record the seasonal and diel presence of minke
whale pulse trains. Minke whales were detected from May to November, with
most detections occurring in June, July and October. No acoustic detections
were made in December, January or in the month of April, whilst no data
were available for February and March. This pattern of acoustic presence
supports available visual data and suggested an absence of minke whales
from the study area during winter. Minke whale acoustic presence showed a
statistically significant diel pattern, with a detection peak during night
time. This study established the acoustic detectability of minke whales in
the North Sea and highlights the potential of using passive acoustic
monitoring to study the seasonal presence and spatial distribution of minke
whales in the North Sea and wider Northeast Atlantic.

I am happy to provide a pdf copy.
Cheers, Denise
