| Zusammenfassung |
| While the concept of oceanic heat transport – or rather heat transport
divergence – is well known, it is sometimes applied inaccurately. Often
so-called "heat transports" are computed across a partial section which
means that the volume flow through such a section is not zero. In this case
the "heat transports" depend entirely on the choice of the temperature
scale. The consequences of such arbitrariness are demonstrated with a simple
calculation exercise for the passages to the Arctic Ocean. To circumvent the
arising difficulties for the Fram Strait in the Arctic we propose a stream
tube concept to define a net zero volume flow section which can, with coarse
assumptions, be used to determine oceanic heat transport by the portion of
Atlantic water flow that passes through Fram Strait. Weaknesses of this
approach and consequences for observational strategies are discussed. |
