Looking at the Bathymetry Leading to South Sound¶

Is the lack of connectivity the reason why we are not seeing deep water in South Sound?

In [35]:

from IPython.display import Image
import matplotlib.pyplot as plt
import xarray as xr

Chart of Bathymetry¶

The soundings are in fathoms. 25 fathoms = 46 m

Our Bathymetry¶

In [3]:

bathy = xr.open_dataset('/home/sallen/MEOPAR/grid/bathymetry_201702.nc')

In [40]:

bathy.Bathymetry.plot(cmap='gist_ncar');

In [41]:

bathy.Bathymetry[5:35, 160:190].plot(cmap='gist_ncar', vmin=45, vmax=60);

In [42]:

bathy.Bathymetry[5:35, 160:190].plot(cmap='gist_ncar_r', vmin=30, vmax=45, figsize=(8, 7));
plt.plot(181-160, 22-5, 'ro')
plt.plot(178-160, 20-5, 'bo');
plt.plot(173-160, 18-5, 'ko');

Yes there are multiple connection breaks at the depth of 45 m.
Need to deepen, to 45 m, the three circled points above.
