Welcome to SMC.
I can comment on a few of these companies. I love dividend stocks also, BadThad is right though, dividends yields can be misleading. Here goes:
Frontline (FRO) Diana (DSX) and Genco (GNK) are all dry bulk shipping companies and have been absolutely hammered with the spot rate of renting these ships has plummeted in the last 2 months. DSX just announced that they suspended their dividend right now until things turn around. FRO, along with NAT (Nordic American Tanker) are the 2 best players in this field for consistent dividends which are usually double digit in nature. Be careful, if the spot rental rates stay down because of the global economy slowing down, these guys could be in trouble to maintain the dividend payout.
Atlas (ATN) is an energy trust headquartered in PA and is big in the natural gas business, They have a real big stake in the Marcellus Shale nat gas region which may be a big boom business. Energy trusts are structured to pay out a large percentage of profits to unitholders and have different tax consequences than traditional dividend payouts. I don't know much about the rest except that I believe Mesabi is also a 'Royalty Trust' and is involved in ore mining in the southwestern US and is similar to Atlas in structure.
Hope this helps you some
