The reference to subduction is a response to a claim by an evolutionist that subduction did remove it. So at this point Humphreys is simply dealing with the only mechanism the evolutionist had given him at the time.
Actually, it's an unsolicited claim by Humphreys in response to nothing in particular. So it's his responisbility to be familiar with the theory he's critcising. He isn't, or he's suppressing relevant information.
Strike one.

Fine - but what is the average rate per year at which these processes occurs? Without an estimate of the average rate per year at which they occur, there is no way to estimate their net effect.
Cuts both ways. In the absence of rate information (and I don't know if there is no rate information; I wouldn't accept the anonymous author's word), nobody can estimate the effect of the processes. Especially Humphreys can't. So his claim that there's too much sediemnt is unfounded. Given the vast amount of other evidence for an old Earth and slow tectonic processes, the best Humphreys can come up with is "not proven for this particular process". Yet he claims proof.
Strike two.

According to Uniformitarian theory, over the last 12 million years this effect would account for at most 1% of the total. This stretches it only to 12.12 million years. In other words this effect is insignificant to the problem.
Reference:Continental Drift
The simple fact is that for the oceans to be 3 billion years old the average accumulation of mud would have to be only 96 million tons per year. This means that the methods of removal suggested in point number 1 would have to remove on average 23.9 billion tons of mud per year.
The reference to whic they link is irrelevant.
No calculations are presented or refered to in support of the numerical claims. That is, they appear to be made up out of thin air.
Oh, and mainstream science doesn't claim that the oceans are anywhere near three billion years old; Isaak explicitly pointed that out, the reference linked to from your reference shows it clearly. There have been oceans for many billions of years, but that's something else entirely.
Strike three.
