Studying the deep ocean is difficult. Accessing even the surface requires special technologies and training; reaching down into the depths to sound or sample is harder still. Technology is not a simple solution; the scientist must have some sense of what they are looking for. How you imagine the bottom decides the length of your line, the design of your samplers, and your interpretation of the results.
This presents a conundrum when teaching the history of ocean science. Students often think of science as establishing factual certainty, forgetting, while investigators inch their way toward new interpretations of the world, that certainty and facts are neither guaranteed nor immediate outcomes. Then there is the difficulty we moderns have in stepping out of our current circumstances to understand the past. Finally, there’s the ocean itself.
