Nice shots it appears you've warm toned many of your black and whites
(my monitor) (selenium filter?) and there are skies and water. You might
try Blue toning those pixels instead. Just soak them in a solution of
Kodak Blue Toner T-26. 
Or try the Ansco Formula:

GOLD TONED Ansco 231

Water (125 deg F or 52 deg C)	750.0 ml
*Ammonium Thiocyanate	105.0 grams
Gold Chloride, 1% Solution	60.0 ml
Add cold water to make	1.0 liter

*May be substituted by:
Sodium Thiocyanate	110.0 grams
or
Potassium Thiocyanate	135.0 grams

1 gram of Gold Chloride dissolved in 100 ml of water will make a 1%
solution.

You'll find 16 bit images require more time or a hotter solution than 8 bit!
