## Introduction

The coastal oceanography course is divided in two sections. A first section addresses the specificities of the coastal ocean from a hydrodynamic point of view. The second section addresses data analysis techniques in oceanography, with a special emphasis in the coastal ocean. The materials will be uploaded after the end of each section.

## Materials

The image and captions point to the slides shown so far during the lessons:

Reading assignments: Coastal Oceanography: Franks et al 2013, Washburn et al 2013

The slides shown during the RACE introduction are here

## Software

• Data visualisation/analysis

## Exercices

### Currents in Calvi Bay

• RACE query example file [1]
• Stations with currents data in the Calvi Bay:

1. Extract all current data (speed and direction) from the RACE database (see figures above)
2. Transform speed and direction into North-South and East-West currents.
3. Study the main currents in the Bay of Calvi:
• Import the average currents for each location into ODV
• Draw in a map the average currents at each of the locations
• Calculate histograms of current direction at each location and compare with the currents in the map

### Temperature and salinity variability in Calvi Bay

CTD data taken during 2014 at the submarine Canyon (depth ~100m) will be analysed

• Install the Seabird software (Windows only)
• Follow these instructions to transform the binary data into ascii data, and to import the data into ODV.
• Study variability of temperature and salinity in Calvi Bay: how do these variables change with time? and with depth? Are there any extreme events? ...
• Vertical sections (time/depth)
• T/S diagrams
• Individual profiles
• ...

### Air-sea fluxes

• A brief explanation about the calculation of air-sea fluxes
• Data for 2014.

## Reference books and websites

• Introduction to the Physical and Biological Oceanography of Shelf Seas. 2012. J.H. Simpson and J. Sharpless. Cambridge. 448pp
• Data Analysis Methods in Physical Oceanography. 2001. W.J. Emery and R.E. Thomson. Elsevier Science Inc. 400 pp.

## Assessment

The Coastal Oceanography course will be assessed in two parts: an exam about a theoretical aspect in coastal oceanography, and an exam about data analysis in coastal oceanography.
