Building a data station


#1

So i am building a data collecting station to receive information on depth, temperature, oxygen levels and video feed. I have a general idea on how im gonna make it but the problem is that i want to it be able to send ths information wirelessly so I dont have to keep going out and pluging it in to a laptop. So I though of a top side information sending thing and i need help making it. Any ideas?

By the way this data collecting station is going to be built in a plastic oil drum and sent out to the bottom of the ocean while being tetherd to this top side data sending buoye.
