Can you link the articleAccording to Dana Riddle's article (that states PAR is probably not the best measurement) - at noon - at the ocean surface ON A CLOUDY DAY - the PAR is 950. at 10 feet its 550. It levels off at 250 PAR at 30 feet or so. At 10 feet on a sunny day the PAR is higher than 400 for 80+ percent of the day. So - I think that tells a story.
