% grab only what we are interesting in, in this case:
% note: assuming data are numeric
latitude = cell2mat(log_data(2:end,lat_idx));

%% plot
% prep figure

% plot the data, colored by level of dissolved oxygen
plot(longitude, latitude, 'b-', 'LineWidth', 3)

% make all text in the figure to size 16
