Sightings of individually identified humpback whales by sex (one location/day; dependent calves excluded) in the Stellwagen Bank area from September 22 to October 6, 2006.

<p>Data courtesy Jooke Robbins (CCS), collected by Provincetown Center for Coastal Studies (CCS) and the Whale Center of New England (WCNE).</p

Received level (RL) measurements over full bandwidth of OAWRS FM pulses, ambient noise (NL) measurements over the same bandwidths, signal-to-noise ratios (SNR) and signal excess (SE) (mean±SD).

<p>N = 677.</p

Summary of OAWRS FM pulse characteristics (mean±SD), as measured from spectrograms (FFT: 512 samples, Hanning window, 75% overlap) and waveforms of MARU recordings on October 1–3, 2006 (sample rate: 2000 Hz, recording depth: 30–40 m).

<p>N = 60.</p

Sightings of baleen whales in the Gulf of Maine during right whale aerial surveys conducted by the Northeast Fisheries Science Center (NEFSC) during September 15 to October 17, for years: 1998, 2002–2008 and 2010.

<p>FIWH  =  fin whale, HUWH  =  humpback whale, MIWH  =  minke whale, RIWH  =  right whale, SEWH  =  sei whale, UNFS  =  unidentified fin or sei whale, UNLW  =  unidenitified large whale.</p

Characteristics of OAWRS signals recorded on MARUs deployed in the Stellwagen Bank National Marine Sanctuary.

<p>(a) Mean frequency spectrum, showing local peaks at center frequencies (approx. 415, 735, 950 Hz) of recorded OAWRS FM pulses. (b) Spectrogram (FFT: 512, Hanning window, 75% overlap) of the same pulses as shown in (a). Time interval between successive signals was changed for display purposes; dB scale is relative.</p

Box-and-Whisker plot of minutes/day containing humpback whale song for 33 days ‘before-during-after’ OAWRS FM pulse transmissions in 2006, and for the same 33 calendar days in 2008 and 2009.

<p>Lower and upper bounds of boxes represent lower and upper quartiles, respectively. Solid lines represent medians and non-filled circles are means. Whiskers represent furthest data points within 1.5× interquartile range (IQR) of the lower and higher quartile, respectively. Filled dots are outliers.</p
