− | * Few empirical field studies compare the predicted and observed hydrocarbon column heights. This is worrisome because idealized laboratory experiments have significant errors in the predicted hydrocarbon column heights. | + | * Few empirical field studies compare the predicted and observed [[hydrocarbon column]] heights.
