The discipline covers marine ecosystems, coastal hazards such asبەرزبوونەوەی شەپۆلی زریان, erosion andsea-level rise, ocean observation, and the communities, fisheries, ports and blue economy that depend on the ocean.
Courses in development extend the scope to further subjects: Ocean warming, acidification and marine heatwaves; Fisheries and aquaculture risk; Ocean governance beyond national jurisdiction.

The subject, methods and measures and debates and bodies
The field and its scope
For coastal planners, port and fisheries managers, marine scientists and analysts of coastal risk who need to read a sea-level projection, aبەرزبوونەوەی شەپۆلی زریانreturn level or an ocean heat record and know what each can support.
Quantities and units
Methods and their limits
Each method is listed with what it assumes and where it fails.
What the field debates
Bodies that set practice, and the data they publish
Bodies and standards are named so learners can find and apply their published work; the Academy teaches their use and links to the publisher, and no affiliation is implied.
05The method
From a centimetre of sea level to a flooded street: how a rising mean turns a rare surge into a frequent one, and what a defence must be
Mean sea level rises by an amount the ice and the ocean set; extreme sea levels ride on that mean, so the surge height that once returned every 100 years returns exponentially more often as the mean rises; the return period of a defence being overtopped is the quantity a coastal decision uses.
Sources:Vousdoukas et al., Global probabilistic projections of extreme sea levels show intensification of coastal flood hazard(2018); Hunter, A simple technique for estimating an allowance for uncertain sea-level rise (2012); Kopp et al., Probabilistic 21st and 22nd century sea-level projections at a global network of tide-gauge sites (2014); Hallegatte et al., Future flood losses in major coastal cities (2013); IPCC, Special Report on the Ocean and Cryosphere in a Changing Climate (2019).
