Most people burn around 6 calories per minute on a sustained basis through moderate exercise, and up to 10 calories per minute with more vigorous exercise. A pretty fit person pushing themselves might burn 12-13.
The type of exercise is far less relevant to calorie burn - what matters is how hard you are pushing yourself.
There is an entry in the My Fitness tracker for "Water aerobics".

Because LA F. has a lap pool, my pool workout is a combination of floor aerobics, stretching, walking, hoping, etc. I spend 45 to 60 minutes at it. Also, I do some paddling with a noodle; a dozen or so laps. Any idea about caloric burn calculation?
