Did British and Germans and the rest of ESA members salvage it from the ocean or will it stay as trash in the ocean ? So much money so much power ... yet all we can to is burn it a little in the atmosphere and let the rest fall into the ocean. Ocean is full of life... lets not forget that. Anyway the solution could be a repairable satellite or removable by some device like space shuttle... ESA has the money, scientists... so on. Space agencies should join in the effort and solve such things together if money is a problem or lack of technology.

the total volume of all oceans is roughly 1.335 bn km^3. the volums of this sattelite is ~6.612m^3, which is about 4.952*10^-16 % of the total ocean volume.
i think it will be fine.

The article seems to imply otherwise, but I suspect not much actually reached the surface. Re-entry is extreme and the majority of it would've vapourised in the atmosphere.

A shuttle launch to repair or retrieve an end-of-life satellite seems like it would prove rather worse for the environment with the thousand-plus tonnes of fuel, including solid fuel boosters and the 30 tonnes of burned-up fuel tank that also falls in the sea than dropping what remains of a compact car's (the Aeolus dry mass is 1200kg) worth of metal after an unshielded reentry.
