North Atlantic Right Whale Calving Season is Here! Each year, pregnant females make their way south along the Atlantic coast to Florida-Georgia to give birth and nurse their young during the winter months (Nov 15-Apr 15). Calving season is a vulnerable time for right whales. Mother-calf pairs spend most of their time at or near the surface of the water but are often difficult to see despite their large size. Adult females face extremely high energetic demands associated with pregnancy and nursin

Blue whale vocalizations are very low frequency sounds with some in the 15 Hz range. These tones characteristically travel long distances due to the high power, but also due to very long-wavelengths (over 300 feet for 15 Hz). This enables their songs to be heard thousands of miles from the source. We can assume that the projection distance is important (Nature can be extravagant, but she is never wasteful), but we can only speculate why they need to broadcast their songs across ocean basins.
