Different Required Stuff, Unusual Treasure, Required Areas, Shipwreck Stuff, & More Mystery Stuff
When you've got a mission, you need different stuff. For one thing, you may need more boats so that when you're checking out shipwrecks, someone else can look for these wrecks! You also have to hire crews to man these ships, and check out the data gathered by the sonar fish and magnetic-scanning device that's also used with the fish.
You also need money. Hey, you have to get those objects somehow! And something is always due to break eventually, and you need a way to buy those repairs. If not, something could go wrong. For example, when you're doing the sonar fish and magnetic-scanning device, you need to keep the speed constant and the ship going in a straight direction, which can depend heavily on the auto-pilot. If the auto-pilot breaks, well... the whole operation gets messed up, and getting the sonar fish and magnetic-scanning device may become not only a lot more harder, but dangerous for people and the devices. So you need to go on land, and you need money to buy the new auto-pilot system, or other broken stuff!
Sometimes, you find stuff that is valuable. And I'm not just talking silver and gold, though those are big items. Lead can be very valuable! I know it's hard to believe, but it's true! Over long periods of time, lead loses particles which let loose alpha waves. These pieces of lead, called low-alpha lead, are very good in the electronics area, since they're very good objects to make computer chips out of. So low-alpha lead can be very valuable, depending on how low-level the low-alpha lead is.
And sometimes lead can have clues to the shipwreck! Metal ingots, when they're made, are imprinted with the maker's mark. This can help narrow down the date of when the ship went down. Of course, they don't always have dates, but different marks or letters. Since you can't always tell what it means right away, you need to figure out what it means. Here comes in the good ol' Internet, and these treasure-hunters usually have a library aboard their ship that help to figure out different clues.
Despite a good deal of depending on sea-bound wrecks, a good deal of stuff is dependent on land operations. You have to send things to labs to be checked out. Sometimes, you have to send stuff to other continents for the right labs and such!
The shipwreck can cause trouble for expeditions. Take subs and German U-boats! Sometimes the torpedoes are still there, and you just don't know how explosive those things are. Or even the state the explosives are in, so there's no way of telling if they're more liable to explode or not.
And fishing expeditions can accidentally cause trouble too. Their fishing nets are very heavy, and can mess up a shipwreck. If the ship is torn enough, it can have a lot of sharp points which can tear tubes and certain stuff and destroy certain stuff in an R.O.V. Plus, sometimes the nets stick around. These can tangle up the R.O.V., and get the robot stuck. Not good!
And get this... fish themselves can cause problems! Shipwrecks are good hiding places, acting like reefs, despite being artificial. So a lot of fish may come over and live in a shipwreck. However, these schools and groups of fish can get in the way of a R.O.V.'s cameras, especially when there's a lot!
There are some confusing shipwrecks too. Some ships once carried frozen meat or other cargo during war-times (like the World Wars), and were shot down. However, these ships cargoes, despite being weird and not the type of cargo you usually think about when you think "sunken ships", can help solve different mysteries... The animal bones of frozen, sunken steaks, for example, can help people figure out what happens to human bodies and bones while underwater. How? Well, these bones can provide clues to what happen to bones in salt water, especially when tested in labs, whether on-board or on land.
Why would one want to do this? Animals and salt water attack the remains of humans, and don't leave a lot of evidence very quickly. No one really knows what happens, and don't want to touch human remains. Animals bones, though, can be touched & tested a lot without any bad thoughts, and can provide clues on what happens to bones of any type, from both humans and animals.
