So, current estimates of oil leaking in the gulf range from 35K-60K barrels per day, lets say 45K, so that is roughly a large WWII US tanker sinking every 3 days with its entire contents leaking out over 3 days in the exact same spot and repeat this for 20 tankers sinking and counting. The average tanker sinking in the Pacific occured every 5-6 days and was on average smaller then the average WW II US tanker cited in my example. So easily 2-3 times the daily average of oil spilled in the gulf of mexico compared to the oil lost during entire pacific campaign during WW II and all in one location.
Many WW II tankers sunk still contain much of their cargo and are cause for concern even now as they rot away and get ready to spew their cargo.
Not to mention the much larger size of the Pacific Ocean compared to the Gulf of Mexico. Overall, there’s a much larger concentration of oil in the Gulf right now than WWII ever came close to producing.
