Fig. 3: LPR measurements: Rp vs time curves for carbon steel grades CS1-2 and low alloy steel grades LA1-2.

a In laboratory conditions and (b) in seaport conditions. Error bars are not represented for clarity; see text for discussion about accuracy of LPR measurements. Black dot = CS1, black square = CS2, brown-red triangle = LA1 and blue triangle = LA2 (full line = LA2_a, dotted line = LA2_b).
